To determine if 1191 is a prime number or a composite number, we simply look at the factors for 1191.
If the factors of 1191 are only 1191 and 1, then we know that 1191 is a prime number. Otherwise, 1191 is a composite number.
To explain better, if 1191 is only divisible by 1 and 1191, then it is a prime number, and if 1191 is divisible by more than 1191 and 1, then it is a composite number.
The factors of 1191 are as follows:
1, 3, 397, 1191
Therefore, since 1191 is divisible by more than one and itself, the answer to the
question "Is 1191 prime or composite?" is highlighted in blue below.
composite
Is 1192 prime or composite?
