Is 4420 a deficient number?

Here we will explain and calculate if 4420 is a deficient number and its deficiency if applicable.

4420 is a deficient number if the sum of its proper divisors is less than 4420.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 10 + 13 + 17 + 20 + 26 + 34 + 52 + 65 + 68 + 85 + 130 + 170 + 221 + 260 + 340 + 442 + 884 + 1105 + 2210 = 6164.

6164 is not less than 4420. Therefore, 4420 is not a deficient number.

The deficiency of 4420 is 4420 minus the sum of its proper divisors. Thus, the deficiency of 4420 is 4420 - 6164 = No Deficiency
