To determine if 2017 is a prime number or a composite number, we simply look at the factors for 2017.
If the factors of 2017 are only 2017 and 1, then we know that 2017 is a prime number. Otherwise, 2017 is a composite number.
To explain better, if 2017 is only divisible by 1 and 2017, then it is a prime number, and if 2017 is divisible by more than 2017 and 1, then it is a composite number.
The factors of 2017 are as follows:
1, 2017
Therefore, since 2017 is divisible by only one and itself, the answer to the
question "Is 2017 prime or composite?" is highlighted in blue below.
prime
