Is 42 a deficient number?

Here we will explain and calculate if 42 is a deficient number and its deficiency if applicable.

42 is a deficient number if the sum of its proper divisors is less than 42.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 6 + 7 + 14 + 21 = 54.

54 is not less than 42. Therefore, 42 is not a deficient number.

The deficiency of 42 is 42 minus the sum of its proper divisors. Thus, the deficiency of 42 is 42 - 54 = No Deficiency
