Composite Numbers:
A Composite number is a natural number that is counting numbers, that has more than two factors i.e., a Composite number is divisible by more than two numbers. Therefore, we can say that a natural number which is not a prime is a composite number. For example, is divisible by and itself. So, it is a composite number.
The given number is , it has only two factors i.e., .
We can see that has only two factors.
Therefore, is a prime number.
