Is 264 a deficient number?

Here we will explain and calculate if 264 is a deficient number and its deficiency if applicable.

264 is a deficient number if the sum of its proper divisors is less than 264.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 6 + 8 + 11 + 12 + 22 + 24 + 33 + 44 + 66 + 88 + 132 = 456.

456 is not less than 264. Therefore, 264 is not a deficient number.

The deficiency of 264 is 264 minus the sum of its proper divisors. Thus, the deficiency of 264 is 264 - 456 = No Deficiency
