Is 4440 a deficient number?

Here we will explain and calculate if 4440 is a deficient number and its deficiency if applicable.

4440 is a deficient number if the sum of its proper divisors is less than 4440.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 5 + 6 + 8 + 10 + 12 + 15 + 20 + 24 + 30 + 37 + 40 + 60 + 74 + 111 + 120 + 148 + 185 + 222 + 296 + 370 + 444 + 555 + 740 + 888 + 1110 + 1480 + 2220 = 9240.

9240 is not less than 4440. Therefore, 4440 is not a deficient number.

The deficiency of 4440 is 4440 minus the sum of its proper divisors. Thus, the deficiency of 4440 is 4440 - 9240 = No Deficiency
