To determine if 1203 is a prime number or a composite number, we simply look at the factors for 1203.
If the factors of 1203 are only 1203 and 1, then we know that 1203 is a prime number. Otherwise, 1203 is a composite number.
To explain better, if 1203 is only divisible by 1 and 1203, then it is a prime number, and if 1203 is divisible by more than 1203 and 1, then it is a composite number.
The factors of 1203 are as follows:
1, 3, 401, 1203
Therefore, since 1203 is divisible by more than one and itself, the answer to the
question "Is 1203 prime or composite?" is highlighted in blue below.
composite
Is 1204 prime or composite?
