To determine if 603 is a prime number or a composite number, we simply look at the factors for 603.
If the factors of 603 are only 603 and 1, then we know that 603 is a prime number. Otherwise, 603 is a composite number.
To explain better, if 603 is only divisible by 1 and 603, then it is a prime number, and if 603 is divisible by more than 603 and 1, then it is a composite number.
The factors of 603 are as follows:
1, 3, 9, 67, 201, 603
Therefore, since 603 is divisible by more than one and itself, the answer to the
question "Is 603 prime or composite?" is highlighted in blue below.
composite
Is 604 prime or composite?
OK. Now you know that 603 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.
