Is 312 a deficient number?

Here we will explain and calculate if 312 is a deficient number and its deficiency if applicable.

312 is a deficient number if the sum of its proper divisors is less than 312.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 6 + 8 + 12 + 13 + 24 + 26 + 39 + 52 + 78 + 104 + 156 = 528.

528 is not less than 312. Therefore, 312 is not a deficient number.

The deficiency of 312 is 312 minus the sum of its proper divisors. Thus, the deficiency of 312 is 312 - 528 = No Deficiency
