Is 404 a deficient number?

Here we will explain and calculate if 404 is a deficient number and its deficiency if applicable.

404 is a deficient number if the sum of its proper divisors is less than 404.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 101 + 202 = 310.

310 is less than 404. Therefore, 404 is a deficient number.
