Answer 1

***********************************
a) mmc ( 18;42) = 126

18,42: 2
9,21: 3
3,7: 3
1,7: 7
--------------
1,1  = 2.3.3.7 = 6.21 = 126

******************************
b) mmc( 25;65)  = 325

25,65: 5
5,13: 5
1,13: 13
---------------
 1,1  = 5.5.13 = 25.13 = 325

¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨

c) mmc ( 48;12)  = 48

48,12: 2
24,6: 2
12,3: 2
6,3: 2
3,3: 3
---------------
1,1   =  2.2.2.2.3 = 16.3 = 48


************************
d) mmc ( 8;36)  = 72

8,36: 2
4,18: 2
2,9: 2
1,9: 3
1,3: 3
----------------------
1,1 = 2.2.2.3.3 = 8.9 = 72

¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
e) mmc ( 15,27)  = 135

15,27: 3
5,9: 3
5,3: 3
5,1: 5
--------------
1,1   = 3.3.3.5 = 27.5 = 135

***************************
f) mmc ( 9,15,6) = 90

9,15,6: 2
9,15,3: 3
3,5,1: 3
1,5,1: 5
--------------
1,1,1  = 2.3.3.5 = 2.9.5 = 2.45 = 90
