Is 630 a deficient number?

Here we will explain and calculate if 630 is a deficient number and its deficiency if applicable.

630 is a deficient number if the sum of its proper divisors is less than 630.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 5 + 6 + 7 + 9 + 10 + 14 + 15 + 18 + 21 + 30 + 35 + 42 + 45 + 63 + 70 + 90 + 105 + 126 + 210 + 315 = 1242.

1242 is not less than 630. Therefore, 630 is not a deficient number.

The deficiency of 630 is 630 minus the sum of its proper divisors. Thus, the deficiency of 630 is 630 - 1242 = No Deficiency
