Is 4515 a deficient number?

Here we will explain and calculate if 4515 is a deficient number and its deficiency if applicable.

4515 is a deficient number if the sum of its proper divisors is less than 4515.

The sum of its proper divisors is calculated as follows: 1 + 3 + 5 + 7 + 15 + 21 + 35 + 43 + 105 + 129 + 215 + 301 + 645 + 903 + 1505 = 3933.

3933 is less than 4515. Therefore, 4515 is a deficient number.
