Is 10 a deficient number?

Here we will explain and calculate if 10 is a deficient number and its deficiency if applicable.

10 is a deficient number if the sum of its proper divisors is less than 10.

The sum of its proper divisors is calculated as follows: 1 + 2 + 5 = 8.

8 is less than 10. Therefore, 10 is a deficient number.

The deficiency of 10 is 10 minus the sum of its proper divisors. Thus, the deficiency of 10 is 10 - 8 = 2
