Is 710 a deficient number?

Here we will explain and calculate if 710 is a deficient number and its deficiency if applicable.

710 is a deficient number if the sum of its proper divisors is less than 710.

The sum of its proper divisors is calculated as follows: 1 + 2 + 5 + 10 + 71 + 142 + 355 = 586.

586 is less than 710. Therefore, 710 is a deficient number.

The deficiency of 710 is 710 minus the sum of its proper divisors. Thus, the deficiency of 710 is 710 - 586 = 124
