Is 837 a deficient number?

Here we will explain and calculate if 837 is a deficient number and its deficiency if applicable.

837 is a deficient number if the sum of its proper divisors is less than 837.

The sum of its proper divisors is calculated as follows: 1 + 3 + 9 + 27 + 31 + 93 + 279 = 443.

443 is less than 837. Therefore, 837 is a deficient number.
