Perfect numbers are numbers whose proper divisors (the divisors except for the number itself) add up to the number itself. The first four perfect numbers, 6, 28, 496, and 8128 have been known since ancient times. 6 = 1 + 2 + 3 28 = 1 + 2 + 4 + 7 + 14 At least 46 perfect numbers had been discovered before the end of 2008.

Perfect numbers are numbers which equal the sum of their divisors. There are two numbers which fulfill this classification which are less than 30:1 + 2 + 3 = 61 + 2 + 4 + 7 + 14 = 28Perfect numbers can be calculated with the following formula:2n*(2(n+1)-1)For example, the first perfect number is: 21*(22-1) = 6The second perfect number is: 22*(23-1) = 28
