To determine if 1347 is a prime number or a composite number, we simply look at the factors for 1347.
If the factors of 1347 are only 1347 and 1, then we know that 1347 is a prime number. Otherwise, 1347 is a composite number.
To explain better, if 1347 is only divisible by 1 and 1347, then it is a prime number, and if 1347 is divisible by more than 1347 and 1, then it is a composite number.
The factors of 1347 are as follows:
