Is 2130 a deficient number?

Here we will explain and calculate if 2130 is a deficient number and its deficiency if applicable.

2130 is a deficient number if the sum of its proper divisors is less than 2130.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 5 + 6 + 10 + 15 + 30 + 71 + 142 + 213 + 355 + 426 + 710 + 1065 = 3054.

3054 is not less than 2130. Therefore, 2130 is not a deficient number.

The deficiency of 2130 is 2130 minus the sum of its proper divisors. Thus, the deficiency of 2130 is 2130 - 3054 = No Deficiency
