Final answer:
To find the greatest common factor of the given expressions, we need to identify the common factors in all three terms. The greatest common factor is x^3y^3.
Step-by-step explanation:
To find the greatest common factor (GCF) of the given expressions, we need to look for the common factors in all three terms. Let's breakdown each expression into its prime factorization:
- y15y8 = y23
- x3y3 = x3y3
- x8y8 = x8y8
Now, let's identify the common factors:
- The common factor for the exponents of 'y' is y3.
- The common factor for the exponents of 'x' is x3.
So, the GCF of the given expressions is x3y3.
