Is 12 a deficient number?

Here we will explain and calculate if 12 is a deficient number and its deficiency if applicable.

12 is a deficient number if the sum of its proper divisors is less than 12.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 6 = 16.

16 is not less than 12. Therefore, 12 is not a deficient number.

The deficiency of 12 is 12 minus the sum of its proper divisors. Thus, the deficiency of 12 is 12 - 16 = No Deficiency
