Is 603 a deficient number?

Here we will explain and calculate if 603 is a deficient number and its deficiency if applicable.

603 is a deficient number if the sum of its proper divisors is less than 603.

The sum of its proper divisors is calculated as follows: 1 + 3 + 9 + 67 + 201 = 281.

281 is less than 603. Therefore, 603 is a deficient number.
