Least Common Multiple: Part 3

Help students build their number sense as they practice finding the least common multiple (LCM) in this helpful practice worksheet. Designed for fifth- and sixth-grade learners, this worksheet offers students practice finding the least common multiple of 10 unique pairs of whole numbers that range up to 25. They will list the multiples of each number in a given pair and find the smallest number that appears in both lists in order to identify the least common multiple. If students need more review, check out the Least Common Multiple: Part 1 worksheet for an introduction with an outlined example. Then, give them the Least Common Multiple: Part 2 worksheet to practice finding the least common multiple of pairs of numbers less than 18.
