Find the prime factor of each coefficient:
Multiply the prime factors they have in common to reach the greatest common factor.
GCF=2*2=4
Note: the greatest common factor is the factor that divides both numbers without leaving any residue.
Now you can factor the GCF out and rewrite the expression
[tex]\begin{gathered} 16x^2+24x \\ 4(4x^2+6x) \end{gathered}[/tex]
