Is 140 a deficient number?

Here we will explain and calculate if 140 is a deficient number and its deficiency if applicable.

140 is a deficient number if the sum of its proper divisors is less than 140.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 7 + 10 + 14 + 20 + 28 + 35 + 70 = 196.

196 is not less than 140. Therefore, 140 is not a deficient number.

The deficiency of 140 is 140 minus the sum of its proper divisors. Thus, the deficiency of 140 is 140 - 196 = No Deficiency
