Is 1782 a deficient number?

Here we will explain and calculate if 1782 is a deficient number and its deficiency if applicable.

1782 is a deficient number if the sum of its proper divisors is less than 1782.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 6 + 9 + 11 + 18 + 22 + 27 + 33 + 54 + 66 + 81 + 99 + 162 + 198 + 297 + 594 + 891 = 2574.

2574 is not less than 1782. Therefore, 1782 is not a deficient number.

The deficiency of 1782 is 1782 minus the sum of its proper divisors. Thus, the deficiency of 1782 is 1782 - 2574 = No Deficiency
