To determine if 1147 is a prime number or a composite number, we simply look at the factors for 1147.
If the factors of 1147 are only 1147 and 1, then we know that 1147 is a prime number. Otherwise, 1147 is a composite number.
To explain better, if 1147 is only divisible by 1 and 1147, then it is a prime number, and if 1147 is divisible by more than 1147 and 1, then it is a composite number.
The factors of 1147 are as follows:
