To determine if 9966 is a prime number or a composite number, we simply look at the factors for 9966.
If the factors of 9966 are only 9966 and 1, then we know that 9966 is a prime number. Otherwise, 9966 is a composite number.
To explain better, if 9966 is only divisible by 1 and 9966, then it is a prime number, and if 9966 is divisible by more than 9966 and 1, then it is a composite number.
The factors of 9966 are as follows:
1, 2, 3, 6, 11, 22, 33, 66, 151, 302, 453, 906, 1661, 3322, 4983, 9966
Therefore, since 9966 is divisible by more than one and itself, the answer to the
question "Is 9966 prime or composite?" is highlighted in blue below.
