Is 6405 an abundant number?

Here we will explain and calculate if 6405 is an abundant number and its abundance if applicable.

6405 is an abundant number if the sum of its proper divisors is greater than 6405.

The sum of its proper divisors is calculated as follows: 1 + 3 + 5 + 7 + 15 + 21 + 35 + 61 + 105 + 183 + 305 + 427 + 915 + 1281 + 2135 = 5499.

5499 is not greater than 6405. Therefore, 6405 is not an abundant number.
