a)MDC(40,50)      fatorar 40| 2                   50|2

                                        20| 2                    25|5

                                        10|2                      5|5

                                           5|5                       1___

                                            1 _____                 2.5²

                                               2³.5

então MDC (40.50)=2.5=10

b)  MDC(9,12,15)                 9|3                 12|2                      15|3

                                             3|3                   6|2                        5|5

                                              1___               3|3                         1___

                                                3²                   1___                       3.5

                                                                        2² .3 

MDC(9,12,15)=3

c) MDC(16,56,80)                 16|2                  56|2              80|2

                                                8|2                  28|2              40|2

                                                4|2                  14|2              20|2

                                                 2|2                   7|7              10|2

                                                  1____              1___            5|5

                                                   (2²)²                 2³.7             1___

                                                                                               (2²)².5

MDC(16,56,80)=2³=8

a)

40,50: 2
20, 25, 2
10, 25: 2
5, 25: 5
1,5: 5
1,1          =    2.5 = 10

mdc (40,50) = 10
____________________________________

b)
mdc (9,12,15) = 3

9,12,15: 2
9,6,15: 2
9,3, 15: 3
3,1,5: 3
1,1,5: 5
1,1,1
******************************************
c)

16,56,80 : 2
8,28, 40: 2
4,14, 20 : 2
2,7,10: 2
1,7,5: 5
1,7,1: 7
1,1,1              =  2.2.2 = 8

mdc (16,56,80) = 8
