Is 540 a deficient number?

Here we will explain and calculate if 540 is a deficient number and its deficiency if applicable.

540 is a deficient number if the sum of its proper divisors is less than 540.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 5 + 6 + 9 + 10 + 12 + 15 + 18 + 20 + 27 + 30 + 36 + 45 + 54 + 60 + 90 + 108 + 135 + 180 + 270 = 1140.

1140 is not less than 540. Therefore, 540 is not a deficient number.

The deficiency of 540 is 540 minus the sum of its proper divisors. Thus, the deficiency of 540 is 540 - 1140 = No Deficiency
