To determine if 1897 is a prime number or a composite number, we simply look at the factors for 1897.
If the factors of 1897 are only 1897 and 1, then we know that 1897 is a prime number. Otherwise, 1897 is a composite number.
To explain better, if 1897 is only divisible by 1 and 1897, then it is a prime number, and if 1897 is divisible by more than 1897 and 1, then it is a composite number.
The factors of 1897 are as follows:
1, 7, 271, 1897
Therefore, since 1897 is divisible by more than one and itself, the answer to the
question "Is 1897 prime or composite?" is highlighted in blue below.
