Is 1520 an abundant number?

Here we will explain and calculate if 1520 is an abundant number and its abundance if applicable.

1520 is an abundant number if the sum of its proper divisors is greater than 1520.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 8 + 10 + 16 + 19 + 20 + 38 + 40 + 76 + 80 + 95 + 152 + 190 + 304 + 380 + 760 = 2200.

2200 is greater than 1520. Therefore, 1520 is an abundant number.

The abundance of 1520 is the sum of its proper divisors minus 1520. Thus, the abundance of 1520 is 2200 - 1520 = 680
