​

Answer 1

Resposta:

1. MDC (8,10) = 2
2. MDC (18,42) = 6
3. MDC (9,12,15) = 3

Explicação passo-a-passo:

8 , 10 | 2

4 , 5 | 2

2 , 5 | 2

1 , 5 | 5

1, 1 | 2³ * 5 = 2*2*2*5 = 40

______________________

42, 18 | 2

21, 9 | 3

7, 3 | 3

7, 1 | 7

1, 1

MDC = 2 . 3 = 6

_____________

9, 6, 15 | 2

9, 3, 15 | 3 ←

3, 1, 5 | 3

1, 1, 5 |_5

1, 1, 1 | MDC = 3

Answer 2

Resposta:

mdc (8, 10)

D(8)=2 2 2 2

D(10)=2 5

MDC=2

mdc (18,42)

D(18)=2 3 3

D(42)=2 3 7

MDC= 2.3 = 6

mdc (9,12,15)

D(9)= 9 9 3 /

D(12)= 6 3/

D(15)= 15 15 5/

MDC=2 2 ->3<- 3 5

MDC= 3
