Is 2115 a deficient number?

Here we will explain and calculate if 2115 is a deficient number and its deficiency if applicable.

2115 is a deficient number if the sum of its proper divisors is less than 2115.

The sum of its proper divisors is calculated as follows: 1 + 3 + 5 + 9 + 15 + 45 + 47 + 141 + 235 + 423 + 705 = 1629.

1629 is less than 2115. Therefore, 2115 is a deficient number.
