To determine if 7305 is a prime number or a composite number, we simply look at the factors for 7305.
If the factors of 7305 are only 7305 and 1, then we know that 7305 is a prime number. Otherwise, 7305 is a composite number.
To explain better, if 7305 is only divisible by 1 and 7305, then it is a prime number, and if 7305 is divisible by more than 7305 and 1, then it is a composite number.
The factors of 7305 are as follows:
1, 3, 5, 15, 487, 1461, 2435, 7305
Therefore, since 7305 is divisible by more than one and itself, the answer to the
