Is 560 a deficient number?

Here we will explain and calculate if 560 is a deficient number and its deficiency if applicable.

560 is a deficient number if the sum of its proper divisors is less than 560.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 7 + 8 + 10 + 14 + 16 + 20 + 28 + 35 + 40 + 56 + 70 + 80 + 112 + 140 + 280 = 928.

928 is not less than 560. Therefore, 560 is not a deficient number.

The deficiency of 560 is 560 minus the sum of its proper divisors. Thus, the deficiency of 560 is 560 - 928 = No Deficiency
