we can rewrite your monomials as follows: $\Large \begin{gathered} 18{x^5}{y^2} = 2 \times {3^2}{x^5}{y^2} \hfill \\ \\ 27{x^5}{y^8}{w^3} = {3^3}{x^5}{y^8}{w^3} \hfill \\ \end{gathered}$

2. Michele_Laino

now, you have to pick all common factors with the lowest exponent

3. Michele_Laino

for example: is 2 a common factor?

4. anonymous

the correct answer is 9x^5y^2

5. Michele_Laino

that's right!
