Is 1755 a deficient number?

Here we will explain and calculate if 1755 is a deficient number and its deficiency if applicable.

1755 is a deficient number if the sum of its proper divisors is less than 1755.

The sum of its proper divisors is calculated as follows: 1 + 3 + 5 + 9 + 13 + 15 + 27 + 39 + 45 + 65 + 117 + 135 + 195 + 351 + 585 = 1605.

1605 is less than 1755. Therefore, 1755 is a deficient number.

The deficiency of 1755 is 1755 minus the sum of its proper divisors. Thus, the deficiency of 1755 is 1755 - 1605 = 150
