What are multiples

Finding least common multiples (lcm) TO FIND THE LCM WE ARE GOING TO LIST OUT THE MULTIPLES MUCH LIKE WE DID WHEN FINDING gcf. Next, we will circle the smallest number that is in both lists. (number they have in common)

How do I tell the difference between lcm and gcf

Practice lcm on white board Find the lcm of 6 and 5. Find the lcm of 8 and 6 Pair up with a friend and share your answers.

Think pair share Did you get the same answer? If so, what did you both do right If not, who was right and why

Lcm in the real world

Practice in your math notebook Find the lcm of 5 and 7 Find the lcm of 3 and 4 Find the lcm of 3 and 5 Find the lcm of 12 and 9 Explain (in writing) the difference between lcm and gcf.
