Is 620 a deficient number?

Here we will explain and calculate if 620 is a deficient number and its deficiency if applicable.

620 is a deficient number if the sum of its proper divisors is less than 620.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 10 + 20 + 31 + 62 + 124 + 155 + 310 = 724.

724 is not less than 620. Therefore, 620 is not a deficient number.

The deficiency of 620 is 620 minus the sum of its proper divisors. Thus, the deficiency of 620 is 620 - 724 = No Deficiency
