Is 1100 a deficient number?

Here we will explain and calculate if 1100 is a deficient number and its deficiency if applicable.

1100 is a deficient number if the sum of its proper divisors is less than 1100.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 10 + 11 + 20 + 22 + 25 + 44 + 50 + 55 + 100 + 110 + 220 + 275 + 550 = 1504.

1504 is not less than 1100. Therefore, 1100 is not a deficient number.

The deficiency of 1100 is 1100 minus the sum of its proper divisors. Thus, the deficiency of 1100 is 1100 - 1504 = No Deficiency
