Is 375 a deficient number?

Here we will explain and calculate if 375 is a deficient number and its deficiency if applicable.

375 is a deficient number if the sum of its proper divisors is less than 375.

The sum of its proper divisors is calculated as follows: 1 + 3 + 5 + 15 + 25 + 75 + 125 = 249.

249 is less than 375. Therefore, 375 is a deficient number.

The deficiency of 375 is 375 minus the sum of its proper divisors. Thus, the deficiency of 375 is 375 - 249 = 126
