joigus Posted Friday at 03:18 PM Share Posted Friday at 03:18 PM As @KJW said, the aliquot sum: Quote In number theory, the aliquot sum s(n) of a positive integer n is the sum of all proper divisors of n, that is, all divisors of n other than n itself. of any prime number is 1, so no prime number can be perfect. Example: 6=1+2+3=1*2*3 Link to comment Share on other sites More sharing options...
