Answer 1

1 - Vamos Fatorar:

a) mmc (14,10 e 5) = 70

14,10, 5: 2
7, 5, 5: 5
7, 1, 1: 7
1, 1, 1

= 2.5.7
= 10.7
= 70
__________

b) mmc (9 e 12) = 36

9, 12: 2
9, 6: 2
9, 3: 3
3, 1: 3
1, 1

= 2.2.3.3
= 4.9
= 36
___________

c) mmc (4,8 e 12) = 24

4, 8, 12: 2
2, 4, 6: 2
1, 2, 3: 2
1, 1, 3: 3
1,1,1

= 2.2.2.3
= 2^3 . 3
= 8.3
= 24
_____________

d) mmc (24,36) = 72

24, 36: 2
12, 18: 2
6, 9: 2
3, 9: 3
1, 3: 3
1,1

= 2.2.2.3.3
= 8.9
= 72
______________

e) mmc (6 e 10) = 30

6,10: 2
3, 5: 3
1, 5: 5
1,1

= 2.3.5
= 6.5
= 30
_________

f) mmc (10,15 e 20) = 60

10,15, 20: 2
5, 15, 10: 2
5, 15, 5: 3
5, 5, 5: 5
1,1,1

= 2.2.3.5
= 4.15
= 60
________________

g) mmc (6,10 e 15) = 30

6, 10, 15: 2
3, 5, 15: 3
1, 5, 5: 5
1,1,1

= 2.3.5
= 6.5
= 30
