Is 1590 a deficient number?

Here we will explain and calculate if 1590 is a deficient number and its deficiency if applicable.

1590 is a deficient number if the sum of its proper divisors is less than 1590.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 5 + 6 + 10 + 15 + 30 + 53 + 106 + 159 + 265 + 318 + 530 + 795 = 2298.

2298 is not less than 1590. Therefore, 1590 is not a deficient number.

The deficiency of 1590 is 1590 minus the sum of its proper divisors. Thus, the deficiency of 1590 is 1590 - 2298 = No Deficiency
