Definition Error

The alternate definition is awkward/wrong and doesn't make sense. How can a number have a factor larger than itself?

An equivalent condition is that n is perfect if the sum of n's factors that are less than n is equal to n.

Replaced definition with wp ref and text

perhaps this was referring to the method used in the rational arithmetic task?
