Is 3090 a deficient number?

Here we will explain and calculate if 3090 is a deficient number and its deficiency if applicable.

3090 is a deficient number if the sum of its proper divisors is less than 3090.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 5 + 6 + 10 + 15 + 30 + 103 + 206 + 309 + 515 + 618 + 1030 + 1545 = 4398.

4398 is not less than 3090. Therefore, 3090 is not a deficient number.

The deficiency of 3090 is 3090 minus the sum of its proper divisors. Thus, the deficiency of 3090 is 3090 - 4398 = No Deficiency
