Is 40 a deficient number?

Here we will explain and calculate if 40 is a deficient number and its deficiency if applicable.

40 is a deficient number if the sum of its proper divisors is less than 40.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 8 + 10 + 20 = 50.

50 is not less than 40. Therefore, 40 is not a deficient number.

The deficiency of 40 is 40 minus the sum of its proper divisors. Thus, the deficiency of 40 is 40 - 50 = No Deficiency
