Is 725 a deficient number?

Here we will explain and calculate if 725 is a deficient number and its deficiency if applicable.

725 is a deficient number if the sum of its proper divisors is less than 725.

The sum of its proper divisors is calculated as follows: 1 + 5 + 25 + 29 + 145 = 205.

205 is less than 725. Therefore, 725 is a deficient number.
