Is 790 a deficient number?

Here we will explain and calculate if 790 is a deficient number and its deficiency if applicable.

790 is a deficient number if the sum of its proper divisors is less than 790.

The sum of its proper divisors is calculated as follows: 1 + 2 + 5 + 10 + 79 + 158 + 395 = 650.

650 is less than 790. Therefore, 790 is a deficient number.

The deficiency of 790 is 790 minus the sum of its proper divisors. Thus, the deficiency of 790 is 790 - 650 = 140
