Is 564 a deficient number?

Here we will explain and calculate if 564 is a deficient number and its deficiency if applicable.

564 is a deficient number if the sum of its proper divisors is less than 564.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 6 + 12 + 47 + 94 + 141 + 188 + 282 = 780.

780 is not less than 564. Therefore, 564 is not a deficient number.
