Resposta:
a)32 e 48 = MDC( 32,48) = 2.2.2.2 = 16
b)60 e 72 = MDC(60,72) = 2.2.3 = 12
c)75 e 125 = MDC(75, 125) = 5.5 = 25
d)70,90 e 12 = MDC(70, 90, 120) = 2.5 = 10
e)198,126 e 5 = MDC(198, 126) = 2.3.3 = 18
f)28,70 e 84 = MDC(28,70,84) = 2.7 = 14
Explicação passo a passo:
A)
32,48 | 2
16, 24 | 2
8, 12 | 2
4, 6 | 2
2, 3 | 2
1, 3 | 3
1, 1/ MDC( 32,48) = 2.2.2.2 = 16
B)
60, 72 | 2
30, 36 | 2
15, 18 | 2
15, 9 | 3
5, 3 | 3
5, 1 | 5
1, 1/ MDC(60,72) = 2.2.3 = 12
C)
75, 125 | 3
25, 125 | 5
5, 25 | 5
1, 5 | 5
1, 1 / MDC(75, 125) = 5.5 = 25
D)
70, 90, 120 | 2
35, 45 , 60 | 2
35, 45, 30 | 2
35, 45, 15 | 3
35, 15, 5 | 3
35, 5, 5 | 5
7, 1, 1 | 7
1, 1, 1 / MDC(70, 90, 120) = 2.5 = 10
E)
198, 126 | 2
99, 63 | 3
33, 21 | 3
11, 7 | 7
11, 1 | 11
1, 1/ MDC(198, 126) = 2.3.3 = 18
F)
28, 70, 84 | 2
14, 35, 42 | 2
7, 35, 21 | 3
7, 35, 7 | 7
1, 5, 1 | 5
1, 1, 1/ MDC(28,70,84) = 2.7 = 14
