You need to find the GCF (Greatest common factor) and create an equation. So in this case, the gcf of 42 and 48 is 6. So then, put the 6 on the outside because it is the gcf and put the other multiples inside. Since 6x7= 42 and 6x8 =48 then those two go inside the parenthesis. 6 (8+7) Hope that helps!
