We all know this is homework. So you are not getting the answer. Oh, this is homeschooling?? Well, then.......... Just kidding the factor pairs of 18 is 1x18, 9x2, and 6x3.
To find the LCM of two numbers, you first need to find the HCF. In this case, the HCF is clearly x. Next you multiply the numbers together and divide by the HCF. x(6x)/x = 6x. Therefore the LCM of x and 6x is 6x.
