"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

find all the proper divisors of the number. if there is only one (1), then the number is prime. otherwise, add the divisors. if the summation equals the number itself, it's a perfect number.

you can look up on the Sieve of Eratosthenes for effective way of finding a lot of prime numbers.
