Is 618 a deficient number?

Here we will explain and calculate if 618 is a deficient number and its deficiency if applicable.

618 is a deficient number if the sum of its proper divisors is less than 618.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 6 + 103 + 206 + 309 = 630.

630 is not less than 618. Therefore, 618 is not a deficient number.
