what is perfect number means?
perfect number is referring to a number where sum of its proper divisor equal to the number itself, for example
below is some of the proper divisor for given number
number = 2 proper divisor = 1 summation of proper divisor = 1
number = 3 proper divisor = 1 summation of proper divisor = 1
number = 4 proper divisor = 1, 2 summation of proper divisor = 3
number = 5 proper divisor = 1 summation of proper divisor = 1
number = 6 proper divisor = 1, 2, 3 summation of proper divisor = 6
number = 7 proper divisor = 1 summation of proper divisor = 1
number = 8 proper divisor = 1, 2, 4 summation of proper divisor = 7
number = 9 proper divisor = 1. 3 summation of proper divisor = 4

thus, 6 as we can see, clearly there, summation of its proper divisor is equal to the number itself which is 6...can you understand class? easy right...
