To determine if 1838 is a prime number or a composite number, we simply look at the factors for 1838.
If the factors of 1838 are only 1838 and 1, then we know that 1838 is a prime number. Otherwise, 1838 is a composite number.
To explain better, if 1838 is only divisible by 1 and 1838, then it is a prime number, and if 1838 is divisible by more than 1838 and 1, then it is a composite number.
The factors of 1838 are as follows:
1, 2, 919, 1838
Therefore, since 1838 is divisible by more than one and itself, the answer to the
question "Is 1838 prime or composite?" is highlighted in blue below.
