Is 4520 a deficient number?

Here we will explain and calculate if 4520 is a deficient number and its deficiency if applicable.

4520 is a deficient number if the sum of its proper divisors is less than 4520.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 8 + 10 + 20 + 40 + 113 + 226 + 452 + 565 + 904 + 1130 + 2260 = 5740.

5740 is not less than 4520. Therefore, 4520 is not a deficient number.

The deficiency of 4520 is 4520 minus the sum of its proper divisors. Thus, the deficiency of 4520 is 4520 - 5740 = No Deficiency
