Question

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

Explanation:

Step1: Factor 8x and 40y

Factor \(8x\): \(8x = 8\times x\)
Factor \(40y\): \(40y = 8\times5\times y\)

Step2: Identify common factors

The common factor between \(8x\) and \(40y\) is \(8\) (since \(x\) and \(y\) are different variables, they aren't common).

Answer:

A. 8
