1. GCF & LCM - Monomials Monomials include VARIABLES!! For example: 36xy 2

2. GCF Use division and the T chart to find the BIGGEST number they have in common. Use the SMALLEST exponent numbers for the variables they have in common LCM Use multiplication and the T chart to find the SMALLEST number they have in common. Use the BIGGEST exponent numbers for the variables

3. GCF – greatest common factor 1 st - Find the GCF of the numbers 2 nd - use the smallest exponent of all SHARED variables

4. GCF – greatest common factor 1 st - Find the GCF of the numbers 2 nd - use the smallest exponent of all SHARED variables
