Prime Numbers :

Prime numbers are those with just two components, namely the number itself and factor 1. Consider the number 5, which only has the two elements 1 and 5. It is a prime number as a result. Let's look at another instance of the number 6, which has four components: 1, 2, 3, and 6. Therefore, 6 is not a prime number. Now that we've established that the number 1 only has one factor, let's use it as an example. As a result, it is not a prime number because a prime number needs to have exactly two elements. The number 1 is therefore a unique number and neither a prime number nor a composite number.
