Question

Greatest common factor of three univariate monomials. Find the greatest common factor of these three expressions.

Answer 1

5x

Explanation:

To solve this question it is easiest to separate it into 2 parts. First, find the GCF of the coefficient. Between the numbers 35, 5, and 70 the GCF is 5. This is because each number is divisible by 5, and 5 is obviously the greatest factor of 5. Then, find the GCF of
`x^2, x^4` and
`x`. In this case, the GCF is x. This is because the largest number they can all be divided by is x. Finally, put these 2 parts together for the final answer, 5x.
