Is 1150 a deficient number?

Here we will explain and calculate if 1150 is a deficient number and its deficiency if applicable.

1150 is a deficient number if the sum of its proper divisors is less than 1150.

The sum of its proper divisors is calculated as follows: 1 + 2 + 5 + 10 + 23 + 25 + 46 + 50 + 115 + 230 + 575 = 1082.

1082 is less than 1150. Therefore, 1150 is a deficient number.

The deficiency of 1150 is 1150 minus the sum of its proper divisors. Thus, the deficiency of 1150 is 1150 - 1082 = 68
