To determine if 609 is a prime number or a composite number, we simply look at the factors for 609.
If the factors of 609 are only 609 and 1, then we know that 609 is a prime number. Otherwise, 609 is a composite number.
To explain better, if 609 is only divisible by 1 and 609, then it is a prime number, and if 609 is divisible by more than 609 and 1, then it is a composite number.
The factors of 609 are as follows:
1, 3, 7, 21, 29, 87, 203, 609
Therefore, since 609 is divisible by more than one and itself, the answer to the
question "Is 609 prime or composite?" is highlighted in blue below.
composite
Is 610 prime or composite?
