Is 1356 a deficient number?

Here we will explain and calculate if 1356 is a deficient number and its deficiency if applicable.

1356 is a deficient number if the sum of its proper divisors is less than 1356.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 6 + 12 + 113 + 226 + 339 + 452 + 678 = 1836.
