Is 4221 an abundant number?

Here we will explain and calculate if 4221 is an abundant number and its abundance if applicable.

4221 is an abundant number if the sum of its proper divisors is greater than 4221.

The sum of its proper divisors is calculated as follows: 1 + 3 + 7 + 9 + 21 + 63 + 67 + 201 + 469 + 603 + 1407 = 2851.

2851 is not greater than 4221. Therefore, 4221 is not an abundant number.

The abundance of 4221 is the sum of its proper divisors minus 4221. Thus, the abundance of 4221 is 2851 - 4221 = no abundance
