Is 490 a deficient number?

Here we will explain and calculate if 490 is a deficient number and its deficiency if applicable.

490 is a deficient number if the sum of its proper divisors is less than 490.

The sum of its proper divisors is calculated as follows: 1 + 2 + 5 + 7 + 10 + 14 + 35 + 49 + 70 + 98 + 245 = 536.

536 is not less than 490. Therefore, 490 is not a deficient number.

The deficiency of 490 is 490 minus the sum of its proper divisors. Thus, the deficiency of 490 is 490 - 536 = No Deficiency
