Simplifying Logistics Ratios Using Prime Factorization

A logistics analyst is simplifying a freight efficiency ratio of −315770-\frac{315}{770} for a quarterly performance report. Using the prime factorization method, the analyst represents the fraction as −3⋅3⋅5⋅72⋅5⋅7⋅11-\frac{3 \cdot 3 \cdot 5 \cdot 7}{2 \cdot 5 \cdot 7 \cdot 11}. Based on this representation, which two prime numbers are the common factors that appear in both the numerator and the denominator and must be divided out to simplify the ratio?
