      Prime Factorization


          54                                        210


      6  x  9                                    5 x 42


      2 x 3 x 3 x 3                          5  x   6 x 7


       3^3  x  2                              5  x    2 x 3  x   7  


      Using the prime numbers from each set take the highest exponent value


      3^3  x  2  x  5  x  7
