C) 18,30 e 48 D) 18,27 e 45

Answer 1

a)150,300,375----2

75,150,375----2
75,75,375----3
25,25,125----5
5,5,25---------5
1,1,5-------------5
1,1,1---------(2•2•3•5•5•5)=1500.
MMC = 1500.

b)120,132,20-----2
60,66,10--------2
30,33,5---------2
15,33,5--------3
5,11,5----------5
1,11,1----------11
1,1,1----------(2*2*2*3*5*11)=720.
MMC=720.

c)18,30,48-----2
9,15,24------------2
9,15,12-----------2
9,15,6------------2
9,15,3------------3
3,5,1------------3
1,5,1----------------5
1,1,1----------------(2*2*2*2*3*3*5)=720.
MMC=720.

d)18,27,45-------2
9,27,45------------3
3,9,15------------3
1,3,5------------------3
1,1,5------------5
1,1,1-------------(2*3*3*3*5)=270
MMC=270
