Question 10

A perfect number is a positive integer that is equal to the sum of its proper
positive factors. Proper positive factors of a number are positive factors that are
less than the number. For example, 6 = 1 + 2 + 3 is a perfect number because
1, 2 and 3 are the only proper positive factors of 6. Find the next perfect number.
