The document explains how to find the least common multiple (LCM) of two numbers. It defines key terms like product, multiple, and common multiple. It then provides examples of finding the LCM of 3 and 6, 9 and 12, and 4 and 6. For each example, it lists the multiples of each number, circles the common multiples, and identifies the smallest common multiple as the LCM. The overall process is to list multiples, identify common multiples, and select the smallest value from the common multiples as the LCM.

3. What is the product? 7 X 8 = 56

4. What is the product? 8 X 9 = 72

6. Name some multiples of 5 5, 10, 15, 20, 25, 30, 35

7. Name some multiples of 7 7, 14, 21, 28, 35, 42, 49

8. Name some multiples of 4 4, 8, 12, 16, 20, 24, 28

9. Name some multiples of 9 9, 18, 27, 36, 45, 54, 63

14. Find the least common multiple of 9 and 12 Step 1: List the multiples of both numbers (only list the first 8) 9: 9, 18, 27, 36, 45, 54, 63, 72 12: 12, 24, 36, 48, 60, 72, 84, 96
