How do you use factor trees to find the greatest common factor of 12 and 42?
Here are factor trees for 12 and 42: 12 - 2 - 6 - 2 - 3 42 - 2 - 21 - 3 - 7 The leaves in 12's factor tree are: 2, 2, and 3. The leaves in 42's factor tree are: 2, 3, and 7. The longest common sub-sequence of the leaf lists is: 2, 3. Therefore, multiply 2 by 3 and we get that 6 is the gcf of 12 and 42.
