To determine if 3198 is a prime number or a composite number, we simply look at the factors for 3198.
If the factors of 3198 are only 3198 and 1, then we know that 3198 is a prime number. Otherwise, 3198 is a composite number.
To explain better, if 3198 is only divisible by 1 and 3198, then it is a prime number, and if 3198 is divisible by more than 3198 and 1, then it is a composite number.
The factors of 3198 are as follows:
1, 2, 3, 6, 13, 26, 39, 41, 78, 82, 123, 246, 533, 1066, 1599, 3198
Therefore, since 3198 is divisible by more than one and itself, the answer to the
question "Is 3198 prime or composite?" is highlighted in blue below.
