A LCM Challenge...LCM of more than two numbers.

Finding the LCM for three or more numbers is a bit more complicated.  Still, find the GCF first.

Now look at the image below. 

Previously, we just multiplied the GCF by the rest of the prime factors listed.  However, in this case I only multiplied by 5 one time even though the prime 5 is list more than once (see first image).  Can you guess why this is?  Reply to this post!
