Question

(o mmc de 5,10,20 e ) (o mmc de 2,3,4,5,6 e) (o mmc de 2,4,8,12,24 e )

Answer 1

5 10 20 / 2
5 05 10 / 2
5 05 05 / 5
1 01 01

2 * 2 * 5 = 20

==============================================

2 3 4 5 6 / 2
1 3 2 5 3 / 2
1 3 1 5 3 / 3
1 1 1 5 1 / 5
1 1 1 1 1 

2 * 2 * 3 * 5 = 60

==============================================

2 4 8 12 24 / 2 
1 2 4 06 12 / 2
1 1 2 03 06 / 2
1 1 1 03 03 / 3
1 1 1 01 01

2 * 2 * 2 * 3 = 24

Answer 2

m (5) = 0,5,10,15,20,25,30,35,40,45,50,55,60,65 ...
m (10) = 0,10,20,30,40,50,60 ...
m (20) = 0,20,40,60,80,100 ...
mmc (5,10,20) = 20

m (2) = 0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58,60,...
m (3) = 0,3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54,57,60,...
m (4) =0,4,8,12,16,20,24,28,32,36,40,44,48,52,56,60,...
m (6) = 0,6,12,18,24,30,36,42,48,54,60,66,...
mmc (2,3,,5,4 e 6) = 60

m (2) = 0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,...
m (4) = 0,4,8,12,16,20,24,28,32,36,40,44,...
m (8) = 0,8,16,24,32,40,48,56,64,72,80,88,...
m (12) = 0,12,24,36,48,...
m (24) = 0,24,48,62,86,...
mmc ( 2,4,8,12 e 24) = 24
