I have found a a couple of perfect numbers that Mathematicians have missed.

 

@Troy

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

I have actually found all the missing ones. 

 

 

 

 

I will send you the factors to 8,796,090,925,056. Tomorrow 

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.	Euclid
5	13	33550336	8	1456	First seen in a medieval manuscript, Munich, Bayerische Staatsbibliothek, CLM 14908, fol. 33[6]
6	17	8589869056	10	1588	Cataldi[1]
7	19	137438691328	12	1588	Cataldi[1]
8	31	2305843008139952128	19	1772	Euler

 

1+2+3=6

1+2+4+7+14=28

 

I wouldn't even want to calculate the next perfect number, 496, without a computer. 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.

 

 

 

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.

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. 

I'll post two more would you like one bigger.

I figured it out with pen paper and a calculator 

 

131,071 it appears that in have also found Merseme prones that computers haven't found 

@Cynique

@Mel Hopkins

@Chevdove

 

 

Which means that I have found primes and they are probably  infinite. 

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.

 

 

 

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 

My mistake 8,589,869,056

1 2 4 8 16 32 64 128 256 512 1024 2048 4096 8192 16384 32768 65536

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. 

My mistake

check my additions now they are divisible by 7.

 

So I have not found anything.

This is all very fascinating to me and also 'way over my head'!--for now.

But I have been following this thread and planning to ask some questions to some smart people to help be better understand!

 

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. 

@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? 

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".

Yes, it is obviously interesting to them. My question is why? Why would anyone about the next astronomy large number no one can even say

Yes, this is new to me! But I am very interested. 

@Chevdove do you really care when and what the next perfect number is? If so why?

If there are patterns in primes. It changes encryption. and perhaps mathematics.

@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.

Now, that is an amazing thought! 

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.

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

@Mel Hopkins WOW! Only 15 and at Harvard!? Now that is amazing!

Lol! @Chevdove that sounds like. Lifetime Movie Title! Lol!

 

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.

@Mel Hopkins Oh yes!
