GCF LCM Monomials include VARIABLES For example 36

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

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