Find the GCF (greatest common factor) of the following terms.

{11x^2y,55x^2y}

To find the greatest common factor (GCF) of these two terms, we need to identify the highest power of each variable that appears in both terms.

For the variable x, the highest power that appears in both terms is x^2.
For the variable y, the highest power that appears in both terms is y.

Since both terms have the same variables raised to the same powers, the GCF of the two terms is:

x^2y
