Is 70 a deficient number?

Here we will explain and calculate if 70 is a deficient number and its deficiency if applicable.

70 is a deficient number if the sum of its proper divisors is less than 70.

The sum of its proper divisors is calculated as follows: 1 + 2 + 5 + 7 + 10 + 14 + 35 = 74.

74 is not less than 70. Therefore, 70 is not a deficient number.

The deficiency of 70 is 70 minus the sum of its proper divisors. Thus, the deficiency of 70 is 70 - 74 = No Deficiency
