Is 3690 a deficient number?

Here we will explain and calculate if 3690 is a deficient number and its deficiency if applicable.

3690 is a deficient number if the sum of its proper divisors is less than 3690.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 5 + 6 + 9 + 10 + 15 + 18 + 30 + 41 + 45 + 82 + 90 + 123 + 205 + 246 + 369 + 410 + 615 + 738 + 1230 + 1845 = 6138.

6138 is not less than 3690. Therefore, 3690 is not a deficient number.

The deficiency of 3690 is 3690 minus the sum of its proper divisors. Thus, the deficiency of 3690 is 3690 - 6138 = No Deficiency
