Is 1705 a deficient number?

Here we will explain and calculate if 1705 is a deficient number and its deficiency if applicable.

1705 is a deficient number if the sum of its proper divisors is less than 1705.

The sum of its proper divisors is calculated as follows: 1 + 5 + 11 + 31 + 55 + 155 + 341 = 599.

599 is less than 1705. Therefore, 1705 is a deficient number.
