7,7,1/7
1,1,1
MMC = 2.3.5.7 = 210
MMC = 210
b)
90,120/2
45,60/2
45,30/2
45,15/3
15,5/3
5,5/5
1,1
MMC = 2.2.2.3.3.5 = 360
MMC = 360
c)

25,75,50/2
25,75,25/3
25,25,25/5
5,5,5/5
1,1,1
MMC = 2.2.2.3.5.5 = 600
MMC = 600
d)
30,75/2
15,75/3
5,25/5
1,5/5
1,1
MMC = 2.3.5.5 = 150
MMC = 150
e) 66,102/2
33,51/3
11,17/11
1,17/17
1,1
MMC = 2.3.11.17 = 1122
