An integer n>1 is abundant if the sum of its proper divisors is greater n. find the smallest abundant integer.

You can obviously skip over all the prime numbers. Take 4, 6, 8, 9, 10, 12, 14, etc.

4 only has two proper divisors: 1, 2

sum = 3

6 has three: 1, 2, 3

sum = 6

8 also has three: 1, 2, 4

sum = 7

10 has three: 1, 2, 5

sum = 8

12 has five: 1, 2, 3, 4, 6

sum = 16

12 is the least abundant integer.
