Is 150 a deficient number?

Here we will explain and calculate if 150 is a deficient number and its deficiency if applicable.

150 is a deficient number if the sum of its proper divisors is less than 150.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 5 + 6 + 10 + 15 + 25 + 30 + 50 + 75 = 222.

222 is not less than 150. Therefore, 150 is not a deficient number.

The deficiency of 150 is 150 minus the sum of its proper divisors. Thus, the deficiency of 150 is 150 - 222 = No Deficiency
