To determine if 1338 is a prime number or a composite number, we simply look at the factors for 1338.
If the factors of 1338 are only 1338 and 1, then we know that 1338 is a prime number. Otherwise, 1338 is a composite number.
To explain better, if 1338 is only divisible by 1 and 1338, then it is a prime number, and if 1338 is divisible by more than 1338 and 1, then it is a composite number.
The factors of 1338 are as follows:
1, 2, 3, 6, 223, 446, 669, 1338
Therefore, since 1338 is divisible by more than one and itself, the answer to the
question "Is 1338 prime or composite?" is highlighted in blue below.
composite
Is 1339 prime or composite?
