Is 3720 a deficient number?

Here we will explain and calculate if 3720 is a deficient number and its deficiency if applicable.

3720 is a deficient number if the sum of its proper divisors is less than 3720.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 5 + 6 + 8 + 10 + 12 + 15 + 20 + 24 + 30 + 31 + 40 + 60 + 62 + 93 + 120 + 124 + 155 + 186 + 248 + 310 + 372 + 465 + 620 + 744 + 930 + 1240 + 1860 = 7800.

7800 is not less than 3720. Therefore, 3720 is not a deficient number.

The deficiency of 3720 is 3720 minus the sum of its proper divisors. Thus, the deficiency of 3720 is 3720 - 7800 = No Deficiency
