identify the greatest common factor of 50cy and 15ay.

Explanation:

Step1: Factorize the coefficients

Factorize (50) and (15). (50 = 2\times5\times5) (15=3\times5) The greatest common factor of (50) and (15) is (5).

Step2: Analyze the variables

For the variables, both terms have (y). The other variables ((c) in (50cy) and (a) in (15ay)) are different. So the common variable factor is (y).

Answer:

(5y)
