Is 525 a deficient number?

Here we will explain and calculate if 525 is a deficient number and its deficiency if applicable.

525 is a deficient number if the sum of its proper divisors is less than 525.

The sum of its proper divisors is calculated as follows: 1 + 3 + 5 + 7 + 15 + 21 + 25 + 35 + 75 + 105 + 175 = 467.

467 is less than 525. Therefore, 525 is a deficient number.

The deficiency of 525 is 525 minus the sum of its proper divisors. Thus, the deficiency of 525 is 525 - 467 = 58
