To determine if 1151 is a prime number or a composite number, we simply look at the factors for 1151.
If the factors of 1151 are only 1151 and 1, then we know that 1151 is a prime number. Otherwise, 1151 is a composite number.
To explain better, if 1151 is only divisible by 1 and 1151, then it is a prime number, and if 1151 is divisible by more than 1151 and 1, then it is a composite number.
The factors of 1151 are as follows:
