Question

m.m.c (10,14.12 m.m.c (21.35.28) m.m.c (10.9) m.m.c (40.8)​

Answer 1

Resposta:

Explicação passo-a-passo:

a)

10, 12, 14 | 2

5, 6, 7 | 2

5, 3, 7 | 3

5, 1, 7 | 5

1, 1, 7 | 7

1, 1, 1 = 2 x 2 x 3 x 5 x 7 = 420, logo mmc(10, 12, 14) = 420

b)

21, 28, 35 | 2

21, 14, 35 | 2

21, 7, 35 | 3

7, 7, 35 | 5

7, 7, 7 | 7

1, 1, 1 | = 2 x 2 x 3 x 5 x 7 = 420, então, mmc(21, 28, 35) = 420

c)

9, 10 | 2

9, 5 | 3

3, 5 | 3

1, 5 | 5

1, 1 | = 2 x 3 x 3 x 5 = 90, então, mmc(9, 10) = 90

d)

8, 48 | 2

4, 24 | 2

2, 12 | 2

1, 6 | 2

1, 3 | 3

1, 1 | = 2 x 2 x 2 x 2 x 3 =  48, então, mmc(8, 48) = 48

Answer 2

Resposta:

Explicação passo-a-passo:

10,14,12=2

5,7,6=2

5,7,3=3

5,7,1=5

1,7,1=7

1,1,1=M.M.C{(2²).3.5.7}=420)

21,35,28=2

21,35,14=2

21,35,7=3

7,35,7=7

1,5,1=5

1,1,1=M.M.C{(2²).3.7.5}=420)

10,9=2

5,9=5

1,9=9

1,1=M.M.C(2.5.9=90)

40,8=2

20,4=2

10,2=2

5,1=5

1,1=M.M.C{(2³).5}=40)
