Answer:
The greatest common factor of and is 3rd answer
Step-by-step explanation:
The greatest common factor of some numbers is the highest common factor of these numbers
Ex: The highest common factor of 8 and 12 is 4 because the factors of 8 are 1, 2, 4, 8 and the factors of 12 are 1, 2, 3, 4, 6, 12, so the common factors of them are 1, 2, 4 and the highest one is 4
The greatest common factor of some terms of the same variable is the smallest exponent
Ex: The greatest common factor of x² and x³ is x²
∵ The terms are and
∵ The smallest exponent is 5
∴ The greatest common factor of and is
