what is the greatest common factor of 8x and 40y? 8 8xy 320 320xy

Explanation:

Step1: Factorize the coefficients

Factorize (8) and (40). (8 = 2\times2\times2) (40=2\times2\times2\times5) The greatest common factor of (8) and (40) is (2\times2\times2 = 8).

Step2: Analyze the variables

For the variables, (x) and (y) have no common factors (since (x\neq y) and there is no lower - power common variable factor).

Answer:

A. (8)
