Perfect Numbers

Description
|
The first seven perfect numbers are: 6, 28, 496, 8128, 33550336, 8589869056, and 137438691328. There are presently 49 known such numbers, which are defined by the fact that the sum of their divisors is twice the number itself. For example 6 has the divisors: 1, 2, 3, 6, which adds up to 12. There is for now no known odd number that is perfect. But it has been proven that it has to be bigger than 10^1500, if it exists. All even perfect numbers are on the form: 2^(p-1)(2^p-1), where p and 2^p-1 are prime numbers. I have made one small program to demonstrate these numbers.
