Is 180 a deficient number?

Here we will explain and calculate if 180 is a deficient number and its deficiency if applicable.

180 is a deficient number if the sum of its proper divisors is less than 180.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 5 + 6 + 9 + 10 + 12 + 15 + 18 + 20 + 30 + 36 + 45 + 60 + 90 = 366.

366 is not less than 180. Therefore, 180 is not a deficient number.

The deficiency of 180 is 180 minus the sum of its proper divisors. Thus, the deficiency of 180 is 180 - 366 = No Deficiency
