To determine if 8406 is a prime number or a composite number, we simply look at the factors for 8406.
If the factors of 8406 are only 8406 and 1, then we know that 8406 is a prime number. Otherwise, 8406 is a composite number.
To explain better, if 8406 is only divisible by 1 and 8406, then it is a prime number, and if 8406 is divisible by more than 8406 and 1, then it is a composite number.
The factors of 8406 are as follows:
1, 2, 3, 6, 9, 18, 467, 934, 1401, 2802, 4203, 8406
Therefore, since 8406 is divisible by more than one and itself, the answer to the
question "Is 8406 prime or composite?" is highlighted in blue below.
