A perfect number is an integer, the sum of whose integral factors, including 1, but excluding itself, is equal to itself. In other words, when the sum of a number's proper factors equals itself, it is called a perfect number.
That means that if you add all of any given number's factors (including 1, but not itself), you get that number. 6
Factors: 1, 2, 3, 6
Sum of factors less than itself: 1 + 2 + 3 = 6 28
Factors: 1, 2, 4, 7, 14, 28
Sum of factors less than itself: 1 + 2 + 4 + 7 + 14 = 28
