1. It starts exactly like GCF! LET’S MOVE ON TO LEAST COMMON MULTIPLE!

2. (1)Follow the steps to find the Greatest Common Factor. (2)Multiply the GCF by the last two dividends in the chart. 2 x 2 x 3 x 2 x 3 = 72 LEAST COMMON MULTIPLE 24 12 6 ÷ 2 2 36 18 9 LCM 4 x 12 x 6 = 72 = x 6 3 2 3 3 12 x

3. (1)Follow the steps to find the Greatest Common Factor. (2)Multiply the GCF by the last two dividends in the chart. 2 x 3 x 3 x 1 x 5 = 90 LEAST COMMON MULTIPLE 18 9 3 ÷ 3 2 90 45 15 LCM 6 x 18 x 5 = 90 = x 5 5 1 3 3 18 x

4. (1)Follow the steps to find the Greatest Common Factor. (2)Multiply the GCF by the last two dividends in the chart. 2 x 5 x 5 x 9 = 450 LEAST COMMON MULTIPLE 50 25 5 ÷ 5 2 90 45 9 LCM 10 x 10 x 45 = 450= x 45

5. (1)Follow the steps to find the Greatest Common Factor. (2)Multiply the GCF by the last two dividends in the chart. 2 x 2 x 2 = 8 NOW, YOU TRY! 4 2 1 ÷ 2 2 8 4 2 LCM 4 x 4 x 2 = 8= x 2
