Is 574 a deficient number?

Here we will explain and calculate if 574 is a deficient number and its deficiency if applicable.

574 is a deficient number if the sum of its proper divisors is less than 574.

The sum of its proper divisors is calculated as follows: 1 + 2 + 7 + 14 + 41 + 82 + 287 = 434.

434 is less than 574. Therefore, 574 is a deficient number.
