**Is 141 a deficient number?**

Here we will explain and calculate if 141 is a deficient number and its deficiency if applicable.

141 is a deficient number if the sum of its proper divisors is less than 141.

The sum of its proper divisors is calculated as follows: 1 + 3 + 47 = 51.

51 is less than 141. Therefore, 141 is a deficient number.

The deficiency of 141 is 141 minus the sum of its proper divisors. Thus, the deficiency of 141 is 141 - 51 = 90
