Is 130 a deficient number?

Here we will explain and calculate if 130 is a deficient number and its deficiency if applicable.

130 is a deficient number if the sum of its proper divisors is less than 130.

The sum of its proper divisors is calculated as follows: 1 + 2 + 5 + 10 + 13 + 26 + 65 = 122.

122 is less than 130. Therefore, 130 is a deficient number.

The deficiency of 130 is 130 minus the sum of its proper divisors. Thus, the deficiency of 130 is 130 - 122 = 8
