Is 100 an abundant number?

Here we will explain and calculate if 100 is an abundant number and its abundance if applicable.

100 is an abundant number if the sum of its proper divisors is greater than 100.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 10 + 20 + 25 + 50 = 117.

117 is greater than 100. Therefore, 100 is an abundant number.

The abundance of 100 is the sum of its proper divisors minus 100. Thus, the abundance of 100 is 117 - 100 = 17
