Is 2040 an abundant number?

Here we will explain and calculate if 2040 is an abundant number and its abundance if applicable.

2040 is an abundant number if the sum of its proper divisors is greater than 2040.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 5 + 6 + 8 + 10 + 12 + 15 + 17 + 20 + 24 + 30 + 34 + 40 + 51 + 60 + 68 + 85 + 102 + 120 + 136 + 170 + 204 + 255 + 340 + 408 + 510 + 680 + 1020 = 4440.

4440 is greater than 2040. Therefore, 2040 is an abundant number.

The abundance of 2040 is the sum of its proper divisors minus 2040. Thus, the abundance of 2040 is 4440 - 2040 = 2400
