Is 315 a deficient number?

Here we will explain and calculate if 315 is a deficient number and its deficiency if applicable.

315 is a deficient number if the sum of its proper divisors is less than 315.

The sum of its proper divisors is calculated as follows: 1 + 3 + 5 + 7 + 9 + 15 + 21 + 35 + 45 + 63 + 105 = 309.

309 is less than 315. Therefore, 315 is a deficient number.
