Is 5481 a deficient number?

Here we will explain and calculate if 5481 is a deficient number and its deficiency if applicable.

5481 is a deficient number if the sum of its proper divisors is less than 5481.

The sum of its proper divisors is calculated as follows: 1 + 3 + 7 + 9 + 21 + 27 + 29 + 63 + 87 + 189 + 203 + 261 + 609 + 783 + 1827 = 4119.

4119 is less than 5481. Therefore, 5481 is a deficient number.
