Is 220 a deficient number?

Here we will explain and calculate if 220 is a deficient number and its deficiency if applicable.

220 is a deficient number if the sum of its proper divisors is less than 220.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 10 + 11 + 20 + 22 + 44 + 55 + 110 = 284.

284 is not less than 220. Therefore, 220 is not a deficient number.

The deficiency of 220 is 220 minus the sum of its proper divisors. Thus, the deficiency of 220 is 220 - 284 = No Deficiency
