It will be a loop if you want to try each number in turn. Make sure you make some way to get out of the loop, or it will run forever.
First, you will have to find all factors of the number and store them in an array. divide the index number by every number between it and 1. There won't be any decimals if it is a factor.
Note: the divisor and the answer will both be factors.
Then, add up all of the items in that array and compare it to the index number. If there is a match, then you've found a perfect number!
If you made it so the index number is part of the array, then you'll have to remove it by halving the added array's result.
The first four perfect numbers are 6, 28, 496 and 8128.
