Is 1617 a deficient number?

Here we will explain and calculate if 1617 is a deficient number and its deficiency if applicable.

1617 is a deficient number if the sum of its proper divisors is less than 1617.

The sum of its proper divisors is calculated as follows: 1 + 3 + 7 + 11 + 21 + 33 + 49 + 77 + 147 + 231 + 539 = 1119.
