# Finding Least Common Multiples & Greatest Common Factors - Crack the Code

Product Description
These fun activities give students practice finding LCMs and GCFs - both important components in successfully adding and subtracting fractions, as well as reducing their answers to lowest terms.

Each puzzle has a bulit-in visual cue using triangles: Triangle pointing up - builds up to the first common multiple. Triangle pointing down - the two multiples look back (down) to the highest common factor they share. This is a great exercise for divisibility rules.

These two no-prep, self-correcting puzzles are perfect for centers or homework, offering students that extra practice extra practice they need.
