To determine if 4518 is a prime number or a composite number, we simply look at the factors for 4518.
If the factors of 4518 are only 4518 and 1, then we know that 4518 is a prime number. Otherwise, 4518 is a composite number.
To explain better, if 4518 is only divisible by 1 and 4518, then it is a prime number, and if 4518 is divisible by more than 4518 and 1, then it is a composite number.
The factors of 4518 are as follows:
1, 2, 3, 6, 9, 18, 251, 502, 753, 1506, 2259, 4518
Therefore, since 4518 is divisible by more than one and itself, the answer to the
question "Is 4518 prime or composite?" is highlighted in blue below.
