To determine if 2238 is a prime number or a composite number, we simply look at the factors for 2238.
If the factors of 2238 are only 2238 and 1, then we know that 2238 is a prime number. Otherwise, 2238 is a composite number.
To explain better, if 2238 is only divisible by 1 and 2238, then it is a prime number, and if 2238 is divisible by more than 2238 and 1, then it is a composite number.
The factors of 2238 are as follows:
1, 2, 3, 6, 373, 746, 1119, 2238
Therefore, since 2238 is divisible by more than one and itself, the answer to the
question "Is 2238 prime or composite?" is highlighted in blue below.
