To determine if 3518 is a prime number or a composite number, we simply look at the factors for 3518.
If the factors of 3518 are only 3518 and 1, then we know that 3518 is a prime number. Otherwise, 3518 is a composite number.
To explain better, if 3518 is only divisible by 1 and 3518, then it is a prime number, and if 3518 is divisible by more than 3518 and 1, then it is a composite number.
The factors of 3518 are as follows:
