To determine if 3665 is a prime number or a composite number, we simply look at the factors for 3665.
If the factors of 3665 are only 3665 and 1, then we know that 3665 is a prime number. Otherwise, 3665 is a composite number.
To explain better, if 3665 is only divisible by 1 and 3665, then it is a prime number, and if 3665 is divisible by more than 3665 and 1, then it is a composite number.
The factors of 3665 are as follows:
