To determine if 1893 is a prime number or a composite number, we simply look at the factors for 1893.
If the factors of 1893 are only 1893 and 1, then we know that 1893 is a prime number. Otherwise, 1893 is a composite number.
To explain better, if 1893 is only divisible by 1 and 1893, then it is a prime number, and if 1893 is divisible by more than 1893 and 1, then it is a composite number.
The factors of 1893 are as follows:
1, 3, 631, 1893
Therefore, since 1893 is divisible by more than one and itself, the answer to the
question "Is 1893 prime or composite?" is highlighted in blue below.
