To determine if 9906 is a prime number or a composite number, we simply look at the factors for 9906.
If the factors of 9906 are only 9906 and 1, then we know that 9906 is a prime number. Otherwise, 9906 is a composite number.
To explain better, if 9906 is only divisible by 1 and 9906, then it is a prime number, and if 9906 is divisible by more than 9906 and 1, then it is a composite number.
The factors of 9906 are as follows:
1, 2, 3, 6, 13, 26, 39, 78, 127, 254, 381, 762, 1651, 3302, 4953, 9906
Therefore, since 9906 is divisible by more than one and itself, the answer to the
question "Is 9906 prime or composite?" is highlighted in blue below.
