Is 2920 a deficient number?

Here we will explain and calculate if 2920 is a deficient number and its deficiency if applicable.

2920 is a deficient number if the sum of its proper divisors is less than 2920.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 8 + 10 + 20 + 40 + 73 + 146 + 292 + 365 + 584 + 730 + 1460 = 3740.

3740 is not less than 2920. Therefore, 2920 is not a deficient number.

The deficiency of 2920 is 2920 minus the sum of its proper divisors. Thus, the deficiency of 2920 is 2920 - 3740 = No Deficiency
