Is 5390 a deficient number?

Here we will explain and calculate if 5390 is a deficient number and its deficiency if applicable.

5390 is a deficient number if the sum of its proper divisors is less than 5390.

The sum of its proper divisors is calculated as follows: 1 + 2 + 5 + 7 + 10 + 11 + 14 + 22 + 35 + 49 + 55 + 70 + 77 + 98 + 110 + 154 + 245 + 385 + 490 + 539 + 770 + 1078 + 2695 = 6922.

6922 is not less than 5390. Therefore, 5390 is not a deficient number.

The deficiency of 5390 is 5390 minus the sum of its proper divisors. Thus, the deficiency of 5390 is 5390 - 6922 = No Deficiency
