To determine if 1149 is a prime number or a composite number, we simply look at the factors for 1149.
If the factors of 1149 are only 1149 and 1, then we know that 1149 is a prime number. Otherwise, 1149 is a composite number.
To explain better, if 1149 is only divisible by 1 and 1149, then it is a prime number, and if 1149 is divisible by more than 1149 and 1, then it is a composite number.
The factors of 1149 are as follows:
