It doesn't to most people. Integers are classed as deficient, perfect, or abundant.
The divisors of a perfect number (including by convention 1 but not itself) add up to the number.
6 = 3 + 2 + 1 is a perfect number.
12 < 6+4+3+2+1 is abundant.
10 > 5 + 2 + 1 is deficient
As far as I know these properties are mainly just a curiosity. But for example a currency system based on 12 would be useful as you can share things out in more ways. Our old Â£1 = 240d was very shareable :)
