Is 212 a deficient number?

Here we will explain and calculate if 212 is a deficient number and its deficiency if applicable.

212 is a deficient number if the sum of its proper divisors is less than 212.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 53 + 106 = 166.

166 is less than 212. Therefore, 212 is a deficient number.
