Is 522 a deficient number?

Here we will explain and calculate if 522 is a deficient number and its deficiency if applicable.

522 is a deficient number if the sum of its proper divisors is less than 522.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 6 + 9 + 18 + 29 + 58 + 87 + 174 + 261 = 648.

648 is not less than 522. Therefore, 522 is not a deficient number.

The deficiency of 522 is 522 minus the sum of its proper divisors. Thus, the deficiency of 522 is 522 - 648 = No Deficiency
