Given
[tex]15x^2\text{ and 25x}^3[/tex]Solution
The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share.
[tex]\begin{gathered} 15x^2=3\times5\times x\times x \\ 25x^3=5\times5\times x\times x\times x \\ \\ GCF=5x^2 \end{gathered}[/tex]The final answer
[tex]GCF=5x^2[/tex]
