ajuda ae man

Answer 1

a) 20, 30 ÷ 2

10, 15 ÷ 2

5, 15 ÷ 3

5, 5 ÷ 5

1, 1 | 2 x 2 x 3 x 5 = 60

b) 15,20 ---2

15,10---2

15,5----5

3  , 1---3

2*2*5*3=60

c)  6,45|2

         3,45|3  

         1,15|3

          1,5 |5*

          1,1 |=90

d)  (5, 14)

5 , 14 | 5

1 , 14 | 2

1 , 7 I 7

1 , 1 ________ 5*2*7 = 70

e) 7, 3, 15 | 3

7, 1, 5 | 5

7, 1, 1 | 7

1, 1, 1

mmc(7, 3, 15) = 3 x 5 x 7

mmc(7, 3, 15) = 105

f) 2, 3, 7 | 2

1, 3, 7 | 3

1, 1, 7 | 7

1, 1, 1

2×3×7= 42

g) 6,8,12|2

3,4,6|2

3,2,3|2

3,1,3|3

1,1,1

2*2*2*3=

4*2*3=

8*3=

24

mmc =24

h) 9, 15, 10 | 2

9, 15, 5 | 3

3, 5, 5 | 3

1, 5, 5 | 5

1, 1, 1

2 * 3 * 3 * 5 = 6 * 3 * 5 = 18 * 5 = 90.
