A common multiple<span> is a number that is a </span>multiple<span> of two or more numbers. The </span>common multiples<span> of 3 and 4 are 0, 12, 24, .... The </span>least common multiple<span> (</span>LCM) of two numbers is the smallest number (not zero) that is amultiple<span> of both. so to the given </span><span>9(x+2)(2x-1) and 3(x+2) the LCM would be 9</span>(x+2)(2x-1)
