Is 2420 a deficient number?

Here we will explain and calculate if 2420 is a deficient number and its deficiency if applicable.

2420 is a deficient number if the sum of its proper divisors is less than 2420.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 10 + 11 + 20 + 22 + 44 + 55 + 110 + 121 + 220 + 242 + 484 + 605 + 1210 = 3166.

3166 is not less than 2420. Therefore, 2420 is not a deficient number.

The deficiency of 2420 is 2420 minus the sum of its proper divisors. Thus, the deficiency of 2420 is 2420 - 3166 = No Deficiency
