Is 1078 a deficient number?

Here we will explain and calculate if 1078 is a deficient number and its deficiency if applicable.

1078 is a deficient number if the sum of its proper divisors is less than 1078.

The sum of its proper divisors is calculated as follows: 1 + 2 + 7 + 11 + 14 + 22 + 49 + 77 + 98 + 154 + 539 = 974.
