When do I use GCF in real life?

  • Do you want to split things into smaller sections?
  • Are you trying to figure out how many people we can invite?
  • Are you trying to arrange something in rows or groups?

e.g. Brittany is making identical balloon arrangements for a party. She has 32 maroon balloons, 24 white balloons, and 16 orange balloons. She wants each arrangement to have the same number of each color. What is the greatest number of arrangements that she can make if every balloon is used?
