Is 424 a deficient number?

Here we will explain and calculate if 424 is a deficient number and its deficiency if applicable.

424 is a deficient number if the sum of its proper divisors is less than 424.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 8 + 53 + 106 + 212 = 386.

386 is less than 424. Therefore, 424 is a deficient number.
