LCM (lowest common multiple) and GCF (greatest common factor) are very important for deciphering some equations.
The greatest common factor would be 2x.
The LCM is the smallest integer that is evenly divisible by both a and b. For example,LCM (2,3) = 6 and LCM (6,10) = 30.
the LCM is 75n to the power of 4
