Is 270 a deficient number?

Here we will explain and calculate if 270 is a deficient number and its deficiency if applicable.

270 is a deficient number if the sum of its proper divisors is less than 270.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 5 + 6 + 9 + 10 + 15 + 18 + 27 + 30 + 45 + 54 + 90 + 135 = 450.

450 is not less than 270. Therefore, 270 is not a deficient number.

The deficiency of 270 is 270 minus the sum of its proper divisors. Thus, the deficiency of 270 is 270 - 450 = No Deficiency
