Is 650 a deficient number?

Here we will explain and calculate if 650 is a deficient number and its deficiency if applicable.

650 is a deficient number if the sum of its proper divisors is less than 650.

The sum of its proper divisors is calculated as follows: 1 + 2 + 5 + 10 + 13 + 25 + 26 + 50 + 65 + 130 + 325 = 652.

652 is not less than 650. Therefore, 650 is not a deficient number.

The deficiency of 650 is 650 minus the sum of its proper divisors. Thus, the deficiency of 650 is 650 - 652 = No Deficiency
