    Por decomposição conjunta em fatores primos

                14        35       60     70/2
                  7        35       30     35/2
                  7        35       15     35/3
                  7        35         5     35/5
                  7          7         1       7/7
                  1          1         1       1
                                                        mmc(14,35,60,70) = 2^2x3x5x7 = 420

Answer 2

14, 35, 60, 70 | 2
  7, 35, 30, 35 | 2
  7, 35, 15, 35 | 3
  7, 35,   5,   7 | 5
  7,   7,   1,   7 | 7            
  1,   1,   1,   1 | 2.2.3.5.7 ---> 2².3.5.7 = 420


R.: mmc(14, 35, 60, 70) = 420
