To determine if 203 is a prime number or a composite number, we simply look at the factors for 203.
If the factors of 203 are only 203 and 1, then we know that 203 is a prime number. Otherwise, 203 is a composite number.
To explain better, if 203 is only divisible by 1 and 203, then it is a prime number, and if 203 is divisible by more than 203 and 1, then it is a composite number.
The factors of 203 are as follows:
1, 7, 29, 203
Therefore, since 203 is divisible by more than one and itself, the answer to the
question "Is 203 prime or composite?" is highlighted in blue below.
composite
Is 204 prime or composite?
OK. Now you know that 203 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
