Is 2691 a deficient number?

Here we will explain and calculate if 2691 is a deficient number and its deficiency if applicable.

2691 is a deficient number if the sum of its proper divisors is less than 2691.

The sum of its proper divisors is calculated as follows: 1 + 3 + 9 + 13 + 23 + 39 + 69 + 117 + 207 + 299 + 897 = 1677.
