Is 672 a deficient number?

Here we will explain and calculate if 672 is a deficient number and its deficiency if applicable.

672 is a deficient number if the sum of its proper divisors is less than 672.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 6 + 7 + 8 + 12 + 14 + 16 + 21 + 24 + 28 + 32 + 42 + 48 + 56 + 84 + 96 + 112 + 168 + 224 + 336 = 1344.

1344 is not less than 672. Therefore, 672 is not a deficient number.

The deficiency of 672 is 672 minus the sum of its proper divisors. Thus, the deficiency of 672 is 672 - 1344 = No Deficiency
