Is 2440 a deficient number?

Here we will explain and calculate if 2440 is a deficient number and its deficiency if applicable.

2440 is a deficient number if the sum of its proper divisors is less than 2440.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 8 + 10 + 20 + 40 + 61 + 122 + 244 + 305 + 488 + 610 + 1220 = 3140.

3140 is not less than 2440. Therefore, 2440 is not a deficient number.

The deficiency of 2440 is 2440 minus the sum of its proper divisors. Thus, the deficiency of 2440 is 2440 - 3140 = No Deficiency
