Is 501 a deficient number?

Here we will explain and calculate if 501 is a deficient number and its deficiency if applicable.

501 is a deficient number if the sum of its proper divisors is less than 501.

The sum of its proper divisors is calculated as follows: 1 + 3 + 167 = 171.

171 is less than 501. Therefore, 501 is a deficient number.
