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
