1. 24, 60 24 = {1, 2, 3, 4, 6, 8, 12, 24} 60 = {1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60} The GCF is 12. 2. 7, 9 7 = {1, 7} 9 = {1, 3, 9} The GCF is 1. 3. 9, 12, 15 9 = {1, 3, 9} 12 = {1, 2, 3, 4, 6, 12} 15 = {1, 3, 5, 15} The GCF is 3. 4. An example of this is #5. It can help you figure out what the greatest amount you can have is. 5. 14 boys and 21 girls. 14 + 21 = 35 Find the multiples of 35. { 1, 5, 7, 35 } Obviously 35 can't be used, because there will be only 1 group. So the greatest number of groups would be 7, each containing 5 students.
