Is 396 a deficient number?

Here we will explain and calculate if 396 is a deficient number and its deficiency if applicable.

396 is a deficient number if the sum of its proper divisors is less than 396.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 6 + 9 + 11 + 12 + 18 + 22 + 33 + 36 + 44 + 66 + 99 + 132 + 198 = 696.

696 is not less than 396. Therefore, 396 is not a deficient number.

The deficiency of 396 is 396 minus the sum of its proper divisors. Thus, the deficiency of 396 is 396 - 696 = No Deficiency
