Is 3440 a deficient number?

Here we will explain and calculate if 3440 is a deficient number and its deficiency if applicable.

3440 is a deficient number if the sum of its proper divisors is less than 3440.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 8 + 10 + 16 + 20 + 40 + 43 + 80 + 86 + 172 + 215 + 344 + 430 + 688 + 860 + 1720 = 4744.

4744 is not less than 3440. Therefore, 3440 is not a deficient number.

The deficiency of 3440 is 3440 minus the sum of its proper divisors. Thus, the deficiency of 3440 is 3440 - 4744 = No Deficiency
