To determine if 3644 is a prime number or a composite number, we simply look at the factors for 3644.
If the factors of 3644 are only 3644 and 1, then we know that 3644 is a prime number. Otherwise, 3644 is a composite number.
To explain better, if 3644 is only divisible by 1 and 3644, then it is a prime number, and if 3644 is divisible by more than 3644 and 1, then it is a composite number.
The factors of 3644 are as follows:
