Is 450 a deficient number?

Here we will explain and calculate if 450 is a deficient number and its deficiency if applicable.

450 is a deficient number if the sum of its proper divisors is less than 450.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 5 + 6 + 9 + 10 + 15 + 18 + 25 + 30 + 45 + 50 + 75 + 90 + 150 + 225 = 759.

759 is not less than 450. Therefore, 450 is not a deficient number.

The deficiency of 450 is 450 minus the sum of its proper divisors. Thus, the deficiency of 450 is 450 - 759 = No Deficiency
