Is 4125 a deficient number?

Here we will explain and calculate if 4125 is a deficient number and its deficiency if applicable.

4125 is a deficient number if the sum of its proper divisors is less than 4125.

The sum of its proper divisors is calculated as follows: 1 + 3 + 5 + 11 + 15 + 25 + 33 + 55 + 75 + 125 + 165 + 275 + 375 + 825 + 1375 = 3363.

3363 is less than 4125. Therefore, 4125 is a deficient number.

The deficiency of 4125 is 4125 minus the sum of its proper divisors. Thus, the deficiency of 4125 is 4125 - 3363 = 762
