  1. Let’s Move On to Least common multiple! It starts exactly like GCF!

  2. Least Common Multiple • Follow the steps to find the Greatest Common Factor. • Multiply the GCF by the last two dividends in the chart. 2 x 2 x 3 x 2 x 3 = 72 ÷ 24 36 12 18 2 x 4 6 9 2 x 12 3 3 3 2 x 6 LCM 12 x 6 = 72 = 2, 3, 5 & 7

  3. Least Common Multiple • Follow the steps to find the Greatest Common Factor. • Multiply the GCF by the last two dividends in the chart. 2 x 3 x 3 x 1 x 5 = 90 ÷ 18 90 9 45 2 x 6 3 15 3 x 18 3 3 5 1 x 5 LCM 18 x 5 = 90 = 2, 3, 5 & 7

  4. Least Common Multiple • Follow the steps to find the Greatest Common Factor. • Multiply the GCF by the last two dividends in the chart. 2 x 5 x 5 x 9 = 450 ÷ 50 90 25 45 2 x 10 5 9 5 x 45 LCM = 10 x 45 = 450 2, 3, 5 & 7

  5. Now, You Try! • Follow the steps to find the Greatest Common Factor. • Multiply the GCF by the last two dividends in the chart. 2 x 2 x 2 = 8 ÷ 4 8 2 4 2 x 4 1 2 2 x 2 LCM = 4 x 2 = 8 2, 3, 5 & 7
