Is 2490 a deficient number?

Here we will explain and calculate if 2490 is a deficient number and its deficiency if applicable.

2490 is a deficient number if the sum of its proper divisors is less than 2490.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 5 + 6 + 10 + 15 + 30 + 83 + 166 + 249 + 415 + 498 + 830 + 1245 = 3558.

3558 is not less than 2490. Therefore, 2490 is not a deficient number.

The deficiency of 2490 is 2490 minus the sum of its proper divisors. Thus, the deficiency of 2490 is 2490 - 3558 = No Deficiency
