To determine if 491 is a prime number or a composite number, we simply look at the factors for 491.
If the factors of 491 are only 491 and 1, then we know that 491 is a prime number. Otherwise, 491 is a composite number.
To explain better, if 491 is only divisible by 1 and 491, then it is a prime number, and if 491 is divisible by more than 491 and 1, then it is a composite number.
The factors of 491 are as follows:
