To determine if 7398 is a prime number or a composite number, we simply look at the factors for 7398.
If the factors of 7398 are only 7398 and 1, then we know that 7398 is a prime number. Otherwise, 7398 is a composite number.
To explain better, if 7398 is only divisible by 1 and 7398, then it is a prime number, and if 7398 is divisible by more than 7398 and 1, then it is a composite number.
The factors of 7398 are as follows:
1, 2, 3, 6, 9, 18, 27, 54, 137, 274, 411, 822, 1233, 2466, 3699, 7398
