Is 1040 an abundant number?

Here we will explain and calculate if 1040 is an abundant number and its abundance if applicable.

1040 is an abundant number if the sum of its proper divisors is greater than 1040.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 8 + 10 + 13 + 16 + 20 + 26 + 40 + 52 + 65 + 80 + 104 + 130 + 208 + 260 + 520 = 1564.

1564 is greater than 1040. Therefore, 1040 is an abundant number.
