Answer:
Step-by-step explanation:
Given two fractional terms 
. Their common factor is a value or function that can go in both fractional terms. The terms can be written as shown.
It can be seen from the both equations that they both have as one of their factors i.e <em>1/8x is common to both fractional terms</em>. This gives the common factor for the two fractional terms as
-7 is losing the fewest as it is the smallest number, and the number that is to the left of the number line.
