Definition of Perfect Numbers

Meaning of perfect numbers

A perfect number: a number is perfect when the sum of its divisors (except the number itself) equals the given number.

Theorem connecting perfect and prime numbers

Examples of perfect numbers

6 : The divisors of 6 are 1,2,3 & 6. To show that this is a perfect number we could all the divisors except the number itself
- 1+2+3 = 6
