Is 1218 a deficient number?

Here we will explain and calculate if 1218 is a deficient number and its deficiency if applicable.

1218 is a deficient number if the sum of its proper divisors is less than 1218.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 6 + 7 + 14 + 21 + 29 + 42 + 58 + 87 + 174 + 203 + 406 + 609 = 1662.

1662 is not less than 1218. Therefore, 1218 is not a deficient number.

The deficiency of 1218 is 1218 minus the sum of its proper divisors. Thus, the deficiency of 1218 is 1218 - 1662 = No Deficiency
