Is 2166 a deficient number?

Here we will explain and calculate if 2166 is a deficient number and its deficiency if applicable.

2166 is a deficient number if the sum of its proper divisors is less than 2166.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 6 + 19 + 38 + 57 + 114 + 361 + 722 + 1083 = 2406.

2406 is not less than 2166. Therefore, 2166 is not a deficient number.
