Is 80 a deficient number?

Here we will explain and calculate if 80 is a deficient number and its deficiency if applicable.

80 is a deficient number if the sum of its proper divisors is less than 80.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 8 + 10 + 16 + 20 + 40 = 106.

106 is not less than 80. Therefore, 80 is not a deficient number.

The deficiency of 80 is 80 minus the sum of its proper divisors. Thus, the deficiency of 80 is 80 - 106 = No Deficiency
