Is 675 a deficient number?

Here we will explain and calculate if 675 is a deficient number and its deficiency if applicable.

675 is a deficient number if the sum of its proper divisors is less than 675.

The sum of its proper divisors is calculated as follows: 1 + 3 + 5 + 9 + 15 + 25 + 27 + 45 + 75 + 135 + 225 = 565.

565 is less than 675. Therefore, 675 is a deficient number.

The deficiency of 675 is 675 minus the sum of its proper divisors. Thus, the deficiency of 675 is 675 - 565 = 110
