Step 1One way of finding the GCF of two numbers goes as follows:Divide the larger number by the smaller to give a quotient and remainder.If the remainder is 0 then the smaller number is the GCF.Otherwise repeat with the smaller number and the remainder.In our example, we find:            72      54        =    1   with remainder 18            54      18        =    3   with remainder 0So the GCF is 18.
