GCF & LCM -
Monomials
Monomials include VARIABLES!!
For example: 36xy2
GCFUse 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
LCMUse multiplication and the T chart to find the SMALLEST number they have in common.
Use the BIGGEST exponent numbers for the variables
