[tex]24=\textcircled{2} \times \textcircled{2} \times 2 \times \textcircled{3} \\ 60=\textcircled{2} \times \textcircled{2} \times \textcircled{3} \times 5 \\ 36=\textcircled{2} \times \textcircled{2} \times \textcircled{3} \times 3 \\ \\ GCF(24,60,36)=\textcircled{2} \times \textcircled{2} \times \textcircled{3}=12[/tex]
The GCF is 12.

Factors for 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 
Factors for 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36 
Factors for 24 are: 1, 2, 3, 4, 6, 8, 12, 24 

Greatest Common Factor is: 12 


hope this helps!
