Is 198 a deficient number?

Here we will explain and calculate if 198 is a deficient number and its deficiency if applicable.

198 is a deficient number if the sum of its proper divisors is less than 198.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 6 + 9 + 11 + 18 + 22 + 33 + 66 + 99 = 270.

270 is not less than 198. Therefore, 198 is not a deficient number.

The deficiency of 198 is 198 minus the sum of its proper divisors. Thus, the deficiency of 198 is 198 - 270 = No Deficiency
