To determine if 1234 is a prime number or a composite number, we simply look at the factors for 1234.
If the factors of 1234 are only 1234 and 1, then we know that 1234 is a prime number. Otherwise, 1234 is a composite number.
To explain better, if 1234 is only divisible by 1 and 1234, then it is a prime number, and if 1234 is divisible by more than 1234 and 1, then it is a composite number.
The factors of 1234 are as follows:
1, 2, 617, 1234
Therefore, since 1234 is divisible by more than one and itself, the answer to the
question "Is 1234 prime or composite?" is highlighted in blue below.
composite
Is 1235 prime or composite?
