To determine if 67 is a prime number or a composite number, we simply look at the factors for 67.
If the factors of 67 are only 67 and 1, then we know that 67 is a prime number. Otherwise, 67 is a composite number.
To explain better, if 67 is only divisible by 1 and 67, then it is a prime number, and if 67 is divisible by more than 67 and 1, then it is a composite number.
The factors of 67 are as follows:
