Is 808 a deficient number?

Here we will explain and calculate if 808 is a deficient number and its deficiency if applicable.

808 is a deficient number if the sum of its proper divisors is less than 808.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 8 + 101 + 202 + 404 = 722.

722 is less than 808. Therefore, 808 is a deficient number.

The deficiency of 808 is 808 minus the sum of its proper divisors. Thus, the deficiency of 808 is 808 - 722 = 86
