Is 180 an abundant number?

Here we will explain and calculate if 180 is an abundant number and its abundance if applicable.

180 is an abundant number if the sum of its proper divisors is greater than 180.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 5 + 6 + 9 + 10 + 12 + 15 + 18 + 20 + 30 + 36 + 45 + 60 + 90 = 366.

366 is greater than 180. Therefore, 180 is an abundant number.

The abundance of 180 is the sum of its proper divisors minus 180. Thus, the abundance of 180 is 366 - 180 = 186
