Is 550 a deficient number?

Here we will explain and calculate if 550 is a deficient number and its deficiency if applicable.

550 is a deficient number if the sum of its proper divisors is less than 550.

The sum of its proper divisors is calculated as follows: 1 + 2 + 5 + 10 + 11 + 22 + 25 + 50 + 55 + 110 + 275 = 566.

566 is not less than 550. Therefore, 550 is not a deficient number.

The deficiency of 550 is 550 minus the sum of its proper divisors. Thus, the deficiency of 550 is 550 - 566 = No Deficiency
