Question 888833
your expressions are:


(30 * v^2 * u^5 * w^4) and (20v^3 * w^7)


a common denominator of 30 and 20 would be 10 because 30 = 10 * 3 and 20 = 10 * 2


a common denominator of v^2 and v^3 would be v^2 because v^2 = v^2 * 1 and v^3 = v^2 * v


a common denominator of w^4 and w^7 would be w^4 because w^4 = w^4 * 1 and w^7 = w^4 * w^3


your common factor would then be (10 * v^2 * w^4)


your expressions would become:


(10 * v^2 * w^4) * (3 * u^5) and (10 * v^2 * w^4) * (2 * v * w^3)
