Is 2190 a deficient number?

Here we will explain and calculate if 2190 is a deficient number and its deficiency if applicable.

2190 is a deficient number if the sum of its proper divisors is less than 2190.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 5 + 6 + 10 + 15 + 30 + 73 + 146 + 219 + 365 + 438 + 730 + 1095 = 3138.

3138 is not less than 2190. Therefore, 2190 is not a deficient number.

The deficiency of 2190 is 2190 minus the sum of its proper divisors. Thus, the deficiency of 2190 is 2190 - 3138 = No Deficiency
