Delano Posted June 11, 2019 Report Posted June 11, 2019 I have found a a couple of perfect numbers that Mathematicians have missed. @Troy
Troy Posted June 11, 2019 Report Posted June 11, 2019 A couple of them? Get out of here! The 1st perfect number is 6. The 15th is shown below. There are maybe 50 or so known perfect numbers. If you found one smaller than the number below, that was not previously know, that is indeed a discovery! What are you gonna do? 541,625,262,843,658,474,126,544,653,743,913,106,140,856,490,539,031,695,784,603,920,818,387,206,994,158,534,859,198,999,921,056,719,921,919,057,390,080,263,646,159,280,013,827,60543974626278890305730344550582702839513947520776904492443149486172943511312628083790493046274068171796046586734872099257219056946554529962991982343103109262424446354778963544148139171981644160558678809214788667732139875666162471455172696430221755428178425481731961195165985555357393778892340514622232450671597919375737282086087821432205222758453755289747625617939517662442631448031344693508520365758479824753602117288040378304860287362125931378999490033667394150374722496698402824080604210869007767039525923,189,466,627,361,521,277,560,353,576,470,795,225,017,385,830,517,102,860,302,123,489,664,785,136,394,992,890,497,329,214,510,750,597,991,145,622,151,989,934,576,498,429,128
Delano Posted June 11, 2019 Author Report Posted June 11, 2019 I have actually found all the missing ones.
Delano Posted June 11, 2019 Author Report Posted June 11, 2019 I will send you the factors to 8,796,090,925,056. Tomorrow
Troy Posted June 11, 2019 Report Posted June 11, 2019 Hold up let me look something up, cause it can't be that simple.... from Wikipedia: Rank p Perfect number Digits Year Discoverer 1 2 6 1 4th century B.C.[5] Euclid 2 3 28 2 4th century B.C. Euclid 3 5 496 3 4th century B.C. Euclid 4 7 8128 4 4th century B.C.

The last perfect number was discovered in December of last year and it is an astronomically large number. So if you show me a number below 9 million that you claim is a perfect number, I would have no way of verifying it, because I'd need to write a program to do it. You would also need to provide the divisors that you used to prove it is correct. Again, I sure someone else would have found them already -- especially if they are as small as you mentioned. They have computers working on finding additional ones as we speak. This site says that all primes up to exponent 83 million have been verified: https://www.mersenne.org/report_milestones/ it also provides a countdown to verifying the ranges of numbers that are not perfect and that range is already absurdly large.
Delano Posted June 11, 2019 Author Report Posted June 11, 2019 It is not that easy. I will send you the factors in a day or so. Do you work with any mathematicians? I have also figured out a heuristic that may find all of the perfect numbers. Can you guess how many factors there are? I like patterns and numbers I will send you a spread sheet.
Delano Posted June 11, 2019 Author Report Posted June 11, 2019 I like patterns and numbers I will send you a spread sheet.
Delano Posted June 11, 2019 Author Report Posted June 11, 2019 Here's the prime factor 131071. @Troy Can you figure out the other factors? If it is too hard I'll give you a smaller perfect number.
Delano Posted June 11, 2019 Author Report Posted June 11, 2019 I'll post two more would you like one bigger.

Delano Posted June 11, 2019 Author Report Posted June 11, 2019 Which means that I have found primes and they are probably infinite.
Troy Posted June 11, 2019 Report Posted June 11, 2019 No I don't know any mathematicians, but I can read. Also, you are confusing me. You know prefect number ≠ prime number right? What is this number 131,071? I don't think there are any odd perfect numbers.
Delano Posted June 11, 2019 Author Report Posted June 11, 2019 131,071 is a Mersenne prime. 8,796,090,925,056 is a perfect number. So I have found something Mathematicians and computers have missed
Delano Posted June 12, 2019 Author Report Posted June 12, 2019 My mistake 8,589,869,056 1 2 4 8 16 32 64 128 256 512 1024 2048 4096 8192 16384 32768 65536
Troy Posted June 12, 2019 Report Posted June 12, 2019 Del the perfect number, 8,589,869,056, was discovered in the 16th century. It is on the list above I shared from wikipedia. However, I'm impressed that you were able to derive it in your own. I'd encourage you to look into the work that has already heen done on the subject.
Delano Posted June 12, 2019 Author Report Posted June 12, 2019 My mistake check my additions now they are divisible by 7. So I have not found anything.

But I have been following this thread and planning to ask some questions to some smart people to help be better understand!
Delano Posted June 15, 2019 Author Report Posted June 15, 2019 I was wrong but Troy is more of the go to person for science and mathematics . Thanks Troy I found it because I happen to see a pattern in the first three. Which doesn't always work it gives false positives but it doesn't miss any of the numbers.
Troy Posted June 15, 2019 Report Posted June 15, 2019 @Delano is being modest he probably knows more than me. I'd forgotten what a perfect number was until I looked it up. I was only sbke to coreect him because I'd just did a little research. It also stuck me peole have computer actively looking for the next perfect number. It stuck me because I can't figure out the motivation to do it. Is there is a practical application for discovering the next perfect prime?
Delano Posted June 15, 2019 Author Report Posted June 15, 2019 Perhaps it is interesting to them. EmirpsEdit Primes that become a different prime when their decimal digits are reversed. The name "emirp" is obtained by reversing the word "prime". 13, 17, 31, 37, 71, 73, 79, 97, 107, 113, 149, 157, 167, 179, 199, 311, 337, 347, 359, 389, 701, 709, 733, 739, 743, 751, 761, 769, 907, 937, 941,

Troy Posted June 16, 2019 Report Posted June 16, 2019 @Chevdove do you really care when and what the next perfect number is? If so why?

If so why? @Troy I am definitely interested and partly because I never really knew about this concept of 'a perfect number'. So it is intriguing because I do see the history of it now, But, I am trying to figure out now, what really is the importance of this subject and, if, or how it is it used in relation to other concepts.

Delano Posted June 22, 2019 Author Report Posted June 22, 2019 Numbers are integral part of science and without numbers it wouldn't be possible to conduct experiments. If numbers are created and not discovered then irs possible mathematics is built on fiction. https://www.pbs.org/wgbh/nova/article/great-math-mystery/ 2
Mel Hopkins Posted June 27, 2019 Report Posted June 27, 2019 The challenge with numbers is if applied wrongly can destroy us - since the only numbers I experiment with is in cooking - I'll leave it to the professionals and enthusiasts. Speaking of which, my oldest daughter's sister is at Harvard right now because she's some kind of math wiz... she's only 15 - I admire her - she probably knows about perfect numbers and their uses 2

She’s there for a coding program - and just for the summer. She creates software programs. But from what my daughter told me - she probably will be Harvard Bound. 1
