Is 60 a deficient number?

Here we will explain and calculate if 60 is a deficient number and its deficiency if applicable.

60 is a deficient number if the sum of its proper divisors is less than 60.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 5 + 6 + 10 + 12 + 15 + 20 + 30 = 108.

108 is not less than 60. Therefore, 60 is not a deficient number.

The deficiency of 60 is 60 minus the sum of its proper divisors. Thus, the deficiency of 60 is 60 - 108 = No Deficiency
