Press the flag to generate perfect numbers! A perfect number is a number that is equal to the sum of its proper divisors. For example: 28's factors (divisors) are 1, 2, 4, 7, 14, and 28. 28's proper divisors are those that do not include itself: 1, 2, 4, 7, and 14. These numbers add to 28. 1+2+4+7+14=28 Hence, 28 is a perfect number. Note: since these numbers do grow very rapidly, this project is only able to find the first four within a reasonable time period, since the fifth one is 33,550,336.
