Is 1100 an abundant number?

Here we will explain and calculate if 1100 is an abundant number and its abundance if applicable.

1100 is an abundant number if the sum of its proper divisors is greater than 1100.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 10 + 11 + 20 + 22 + 25 + 44 + 50 + 55 + 100 + 110 + 220 + 275 + 550 = 1504.

1504 is greater than 1100. Therefore, 1100 is an abundant number.

The abundance of 1100 is the sum of its proper divisors minus 1100. Thus, the abundance of 1100 is 1504 - 1100 = 404
