The greatest common factor is

Step-by-step explanation:
The given expression is

We need to determine the greatest common factor of the given expression.
The greatest common factor of two numbers is the largest number of the two numbers that divides them both.
Hence, from the given expression, let us common out the highest factor that divides the two numbers.
Thus, we have,

Thus, the largest number that divides both the terms is

Hence, the greatest common factor of the given expression is
