Is 530 a deficient number?

Here we will explain and calculate if 530 is a deficient number and its deficiency if applicable.

530 is a deficient number if the sum of its proper divisors is less than 530.

The sum of its proper divisors is calculated as follows: 1 + 2 + 5 + 10 + 53 + 106 + 265 = 442.

442 is less than 530. Therefore, 530 is a deficient number.

The deficiency of 530 is 530 minus the sum of its proper divisors. Thus, the deficiency of 530 is 530 - 442 = 88
