Is 120 a deficient number?

Here we will explain and calculate if 120 is a deficient number and its deficiency if applicable.

120 is a deficient number if the sum of its proper divisors is less than 120.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 5 + 6 + 8 + 10 + 12 + 15 + 20 + 24 + 30 + 40 + 60 = 240.

240 is not less than 120. Therefore, 120 is not a deficient number.

The deficiency of 120 is 120 minus the sum of its proper divisors. Thus, the deficiency of 120 is 120 - 240 = No Deficiency
