Answer:
[tex]\boxed{\boxed{\sf 3(x+8y)}}[/tex]
Step-by-step explanation:
[tex]\sf 3x+24y[/tex]
Factor out the GCF( Write GFC first, then, in parentheses divide each term by the GCF).
GCF: → 3
[tex]\leadsto\sf \textsf{\:}3\left(\cfrac{3x}{3}\:+\cfrac{24y}{3}\right)[/tex]
Simplify each term in parentheses:
[tex]\leadsto\sf 3(x+8y)[/tex]
