Is 1630 a deficient number?

Here we will explain and calculate if 1630 is a deficient number and its deficiency if applicable.

1630 is a deficient number if the sum of its proper divisors is less than 1630.

The sum of its proper divisors is calculated as follows: 1 + 2 + 5 + 10 + 163 + 326 + 815 = 1322.

1322 is less than 1630. Therefore, 1630 is a deficient number.
