Is 1300 a deficient number?

Here we will explain and calculate if 1300 is a deficient number and its deficiency if applicable.

1300 is a deficient number if the sum of its proper divisors is less than 1300.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 10 + 13 + 20 + 25 + 26 + 50 + 52 + 65 + 100 + 130 + 260 + 325 + 650 = 1738.

1738 is not less than 1300. Therefore, 1300 is not a deficient number.

The deficiency of 1300 is 1300 minus the sum of its proper divisors. Thus, the deficiency of 1300 is 1300 - 1738 = No Deficiency
