Is 138 a deficient number?

Here we will explain and calculate if 138 is a deficient number and its deficiency if applicable.

138 is a deficient number if the sum of its proper divisors is less than 138.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 6 + 23 + 46 + 69 = 150.

150 is not less than 138. Therefore, 138 is not a deficient number.

The deficiency of 138 is 138 minus the sum of its proper divisors. Thus, the deficiency of 138 is 138 - 150 = No Deficiency
