The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers. The least common multiple of 9, 14, and 21 is 126.

The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.The least common multiple of 12, 14, 21, and 28 is 84.

The common multiples of 7, 14, and 21 are the infinite set of multiples of their least common multiple, which is 42. So the common multiplesof 7, 14, and 21 are 42, 84, 126, 168, and so on.Any multiple of 42.

The least common multiple of 14 and 21 is 42.Look at the multiples of 14. They are 14, 28 and 42.Now clearly 14 and 28 are can't be multiples of 21 also so throw them out as candidate for the LCM. However, the next number. 42 is 21x2.We know there is no smaller common multiple because 21x1 did not work so we are done.The LCM is: 42

The Least Common Multiple (LCM) for 49 63 21 is 441.
