Is 1015 a deficient number?

Here we will explain and calculate if 1015 is a deficient number and its deficiency if applicable.

1015 is a deficient number if the sum of its proper divisors is less than 1015.

The sum of its proper divisors is calculated as follows: 1 + 5 + 7 + 29 + 35 + 145 + 203 = 425.

425 is less than 1015. Therefore, 1015 is a deficient number.
