# What do you mean by ABUNDANT Number in math?

An online abundant number definition

An abundant number or excessive number is a number for which the sum of its proper divisors is greater than the number itself.

An abundant number is a number n for which the sum of divisors σ(n)>2n, or, equivalently, the sum of proper divisors (or aliquot sum) s(n)>n.

**Example:** __48 is a abundant number.__

1 and 48

2 and 24

3 and 16

4 and 12

6 and 8

If we leave out the number we started with, 48, and add all the other factors, we get 76.

1 + 2 + 3 + 4 + 6 + 8 + 12 + 16 + 24 = 76

Hence this, 48 is a Abundant Number
