To determine if 3642 is a prime number or a composite number, we simply look at the factors for 3642.
If the factors of 3642 are only 3642 and 1, then we know that 3642 is a prime number. Otherwise, 3642 is a composite number.
To explain better, if 3642 is only divisible by 1 and 3642, then it is a prime number, and if 3642 is divisible by more than 3642 and 1, then it is a composite number.
The factors of 3642 are as follows:
