Is 1210 a deficient number?

Here we will explain and calculate if 1210 is a deficient number and its deficiency if applicable.

1210 is a deficient number if the sum of its proper divisors is less than 1210.

The sum of its proper divisors is calculated as follows: 1 + 2 + 5 + 10 + 11 + 22 + 55 + 110 + 121 + 242 + 605 = 1184.

1184 is less than 1210. Therefore, 1210 is a deficient number.

The deficiency of 1210 is 1210 minus the sum of its proper divisors. Thus, the deficiency of 1210 is 1210 - 1184 = 26
