To determine if 1197 is a prime number or a composite number, we simply look at the factors for 1197.
If the factors of 1197 are only 1197 and 1, then we know that 1197 is a prime number. Otherwise, 1197 is a composite number.
To explain better, if 1197 is only divisible by 1 and 1197, then it is a prime number, and if 1197 is divisible by more than 1197 and 1, then it is a composite number.
The factors of 1197 are as follows:
1, 3, 7, 9, 19, 21, 57, 63, 133, 171, 399, 1197
Therefore, since 1197 is divisible by more than one and itself, the answer to the
question "Is 1197 prime or composite?" is highlighted in blue below.
