Is 210 a deficient number?

Here we will explain and calculate if 210 is a deficient number and its deficiency if applicable.

210 is a deficient number if the sum of its proper divisors is less than 210.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 5 + 6 + 7 + 10 + 14 + 15 + 21 + 30 + 35 + 42 + 70 + 105 = 366.

366 is not less than 210. Therefore, 210 is not a deficient number.

The deficiency of 210 is 210 minus the sum of its proper divisors. Thus, the deficiency of 210 is 210 - 366 = No Deficiency
