To determine if 5403 is a prime number or a composite number, we simply look at the factors for 5403.
If the factors of 5403 are only 5403 and 1, then we know that 5403 is a prime number. Otherwise, 5403 is a composite number.
To explain better, if 5403 is only divisible by 1 and 5403, then it is a prime number, and if 5403 is divisible by more than 5403 and 1, then it is a composite number.
The factors of 5403 are as follows:
