Question

¿Cómo se calcula el MCM y el DCM ? Ejemplos

Answer 1

126 | 2            60 | 2
 63 | 3            30 | 2
 21 | 3            15 | 3
  7 | 7             5 | 5
  1 | 1             1 | 1

126 = 2.32.7                      60 = 22.3.5

MCD = 2.3 = 6



72 | 2             108 | 2           180 | 2
36 | 2              54 | 2            90 | 2
18 | 2              27 | 3            45 | 3
 9 | 3               9 | 3            15 | 3
 3 | 3               3 | 3             5 | 5
 1 | 1               1 | 1             1 | 1

72 = 23.32                          108 = 22.33                    180 = 22.32.5

MCD = 22.32 = 36



70 | 2              60 | 2             50 | 2
35 | 5              30 | 2             25 | 5
 7 | 7              15 | 3              5 | 5
 1 | 1               5 | 5              1 | 1
                     1 | 1

70 = 2.5.7                          60 = 22.3.5                       50 = 2.52

MCD = 2.5 = 10
