what is the greatest common factor of 8x and 40y?\n8\n8xy\n320\n320xy

what is the greatest common factor of 8x and 40y?\n8\n8xy\n320\n320xy
Answer
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
The first term has variable $x$ and the second term has variable $y$. Since $x$ and $y$ are different variables, there is no common variable factor between them.
Answer:
A. 8
