Since s is a multiple of x, the common factors of x and s include x and their common factors. However, since we are looking for the greatest common factor, the only factor that is guaranteed to be the greatest is x, since it is a factor of both x and s, and no other factor can be greater than x. Therefore, the greatest common factor of x and s is x.
