Is 814 a deficient number?

Here we will explain and calculate if 814 is a deficient number and its deficiency if applicable.

814 is a deficient number if the sum of its proper divisors is less than 814.

The sum of its proper divisors is calculated as follows: 1 + 2 + 11 + 22 + 37 + 74 + 407 = 554.

554 is less than 814. Therefore, 814 is a deficient number.
