Given,
[tex]18x^3y^2,9xyz[/tex]To find GCF we will factor constant and variable terms individually,
First factorize 18:
[tex]18=1,2,3,6,9,18[/tex]Factors of 9:
[tex]9=1\times3\times9[/tex]Now,
[tex]\begin{gathered} 18=1,2,3,6,9,18 \\ 9=1,3,9 \end{gathered}[/tex]Now GCF of 18,9 is 9.
GCF of
[tex]x^3=x,x,x[/tex]GCF of
