Is 1683 a deficient number?

Here we will explain and calculate if 1683 is a deficient number and its deficiency if applicable.

1683 is a deficient number if the sum of its proper divisors is less than 1683.

The sum of its proper divisors is calculated as follows: 1 + 3 + 9 + 11 + 17 + 33 + 51 + 99 + 153 + 187 + 561 = 1125.
