Answer 1

Para encontrar o MMC precisa fatororar os números, usando números primos( 2,3,5,7,11..)

a)4,6,8 MMC=24
4,6,8|2
2,3,4|2
1,3,2 |2
1,3,1 |3
1,1,1 | {2×2×2×3}=24

b)3,8,9 MMC=72
3,8,9|2
3,4,9|2
3,2,9|2
3,1,9 |3
1, 1, 3|3
1, 1, 1 | {2×2×2×3×3}=72

c)10, 4, 6 MMC=60
10,4,6|2
5,2,3 |2
5,1,3 |3
5,1, 1 |5
1, 1, 1 | {2×2×3×5}=60

d)9,15,2 MMC=90
9,15,2|2
9,15,1 |3
3,5,1 |3
1, 5, 1 |5
1, 1, 1 | { 2×3×3×5}=90

e)14,18,9 MMC= 126
14,18,9|2
7,9,9 |3
7, 3, 3 |3
7, 1, 1 |7
1, 1, 1 | {2×3×3×7}= 126

f)21,35 MMC=105
21,35|3
7, 35 |5
7, 7 |7
1, 1 | {3×5×7}= 105

Answer 2

4,6,8/2
2,3,4/2
1,3,2/2
1,3,1/3
1,1,1/=2.2.2.3=24

O mmc de 4,6,8 e 24

3,8,9/2
3,4,9/2
3,2,9/2
3,1,9/3
1,1,3/3
1,1,1/=2.2.2.3.3=72
O mmc de 3,8,9 e 72

10,4,6/2
5,2,3/2
5,1,3/3
5,1,1/5
1,1,1/=2.2.3.5=60
O mmc de 10,4,6 e 60

9,15,2/2
9,15,1/3
3,5,1/3
1,5,1/5
1,1,1/=2.3.3.5=90
O mmc de 9,15,2 e 90

14,18,9/2
7 , 9, 9/3
7, 3 , 3/3
7, 1 , 1/7
1 , 1 ,1/=2.3.3.7=126
O mmc de 14,18,9 e 126


21,35/3
7, 35/5
7, 7/7
1, 1/=3.5.7=105
O mmc de 21,35 e 105
