What is the associative property?
(Grouping)- When you are only adding or only multiplying you can group any of the numbers together.
What is the difference between factors and mutiples.
Factors are two ore more number being multiplied together. Multiples are the product of two factors such as skip counting.

Find the error. D.J. and Trina are finding the LCM of 6 and 8. Who is correct? Explain your reasoning.
DJ- LCM = 2 Trina- LCM = 24
Trina is correct. Trina found the LCM while D.J. found the GCF.
