Is 144 a deficient number?

Here we will explain and calculate if 144 is a deficient number and its deficiency if applicable.

144 is a deficient number if the sum of its proper divisors is less than 144.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 6 + 8 + 9 + 12 + 16 + 18 + 24 + 36 + 48 + 72 = 259.

259 is not less than 144. Therefore, 144 is not a deficient number.

The deficiency of 144 is 144 minus the sum of its proper divisors. Thus, the deficiency of 144 is 144 - 259 = No Deficiency
