Is 580 a deficient number?

Here we will explain and calculate if 580 is a deficient number and its deficiency if applicable.

580 is a deficient number if the sum of its proper divisors is less than 580.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 10 + 20 + 29 + 58 + 116 + 145 + 290 = 680.

680 is not less than 580. Therefore, 580 is not a deficient number.

The deficiency of 580 is 580 minus the sum of its proper divisors. Thus, the deficiency of 580 is 580 - 680 = No Deficiency
