Is 441 a deficient number?

Here we will explain and calculate if 441 is a deficient number and its deficiency if applicable.

441 is a deficient number if the sum of its proper divisors is less than 441.

The sum of its proper divisors is calculated as follows: 1 + 3 + 7 + 9 + 21 + 49 + 63 + 147 = 300.

300 is less than 441. Therefore, 441 is a deficient number.
