Can a number have no common factors and why?
When a number has no common factors with another, they are called coprime, and an infinite number of such pairs exist. They include any pair involving a prime number, but also such pairs as 12 and 25. It is a simple matter of the two numbers not having any common factors; there is no complicated technical description or proof required.
