To determine if 3609 is a prime number or a composite number, we simply look at the factors for 3609.
If the factors of 3609 are only 3609 and 1, then we know that 3609 is a prime number. Otherwise, 3609 is a composite number.
To explain better, if 3609 is only divisible by 1 and 3609, then it is a prime number, and if 3609 is divisible by more than 3609 and 1, then it is a composite number.
The factors of 3609 are as follows:
