Is 4018 a deficient number?

Here we will explain and calculate if 4018 is a deficient number and its deficiency if applicable.

4018 is a deficient number if the sum of its proper divisors is less than 4018.

The sum of its proper divisors is calculated as follows: 1 + 2 + 7 + 14 + 41 + 49 + 82 + 98 + 287 + 574 + 2009 = 3164.

3164 is less than 4018. Therefore, 4018 is a deficient number.
