Is 1690 an abundant number?

Here we will explain and calculate if 1690 is an abundant number and its abundance if applicable.

1690 is an abundant number if the sum of its proper divisors is greater than 1690.

The sum of its proper divisors is calculated as follows: 1 + 2 + 5 + 10 + 13 + 26 + 65 + 130 + 169 + 338 + 845 = 1604.

1604 is not greater than 1690. Therefore, 1690 is not an abundant number.

The abundance of 1690 is the sum of its proper divisors minus 1690. Thus, the abundance of 1690 is 1604 - 1690 = no abundance
