Is 1404 a deficient number?

Here we will explain and calculate if 1404 is a deficient number and its deficiency if applicable.

1404 is a deficient number if the sum of its proper divisors is less than 1404.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 6 + 9 + 12 + 13 + 18 + 26 + 27 + 36 + 39 + 52 + 54 + 78 + 108 + 117 + 156 + 234 + 351 + 468 + 702 = 2516.

2516 is not less than 1404. Therefore, 1404 is not a deficient number.

The deficiency of 1404 is 1404 minus the sum of its proper divisors. Thus, the deficiency of 1404 is 1404 - 2516 = No Deficiency
