Is 918 a deficient number?

Here we will explain and calculate if 918 is a deficient number and its deficiency if applicable.

918 is a deficient number if the sum of its proper divisors is less than 918.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 6 + 9 + 17 + 18 + 27 + 34 + 51 + 54 + 102 + 153 + 306 + 459 = 1242.

1242 is not less than 918. Therefore, 918 is not a deficient number.

The deficiency of 918 is 918 minus the sum of its proper divisors. Thus, the deficiency of 918 is 918 - 1242 = No Deficiency
