Use GCF in grouping stories
5th Grade Math practice: A teacher has 24 red beads and 36 blue beads. She wants the greatest number of identical bags with no beads left over. How many bags can she make. Part of factors and multiples (Factors and multiples).
~7 min
Use GCF when the story wants the greatest size of equal groups with no leftovers.
Finding Largest Equal Groups
How many groups of 4 are in 12?
12 ÷ 4 = 3
When a story asks to divide two groups into equal parts with no leftovers, finding the greatest common factor (GCF) tells you the largest possible size for each group.
