72 is abundant. An abundant number's sum of divisors is greater than itself: 36+24+18+12 is already greater than 72.

The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, and 36. These add up to well over 72, and thus 72 is an abundant number.

It is an abundant number, because when you add up its factors besides itself, you don't get a number greater than 72:
1+2+3+4+6+8+9+12+36 = 81
