Is 4380 a deficient number?

Here we will explain and calculate if 4380 is a deficient number and its deficiency if applicable.

4380 is a deficient number if the sum of its proper divisors is less than 4380.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 5 + 6 + 10 + 12 + 15 + 20 + 30 + 60 + 73 + 146 + 219 + 292 + 365 + 438 + 730 + 876 + 1095 + 1460 + 2190 = 8052.

8052 is not less than 4380. Therefore, 4380 is not a deficient number.

The deficiency of 4380 is 4380 minus the sum of its proper divisors. Thus, the deficiency of 4380 is 4380 - 8052 = No Deficiency
