Is 105 an abundant number?

Here we will explain and calculate if 105 is an abundant number and its abundance if applicable.

105 is an abundant number if the sum of its proper divisors is greater than 105.

The sum of its proper divisors is calculated as follows: 1 + 3 + 5 + 7 + 15 + 21 + 35 = 87.

87 is not greater than 105. Therefore, 105 is not an abundant number.

The abundance of 105 is the sum of its proper divisors minus 105. Thus, the abundance of 105 is 87 - 105 = no abundance
