To determine if 9215 is a prime number or a composite number, we simply look at the factors for 9215.
If the factors of 9215 are only 9215 and 1, then we know that 9215 is a prime number. Otherwise, 9215 is a composite number.
To explain better, if 9215 is only divisible by 1 and 9215, then it is a prime number, and if 9215 is divisible by more than 9215 and 1, then it is a composite number.
The factors of 9215 are as follows:
1, 5, 19, 95, 97, 485, 1843, 9215
Therefore, since 9215 is divisible by more than one and itself, the answer to the
