Question

calcule o minimo multiplo comum comum (mmc) dos números 3, 5, 15, e 20.

Answer 1

MMC 3,5,15,20
3,5,15,20      2
3,5,15,10      2
3,5,15,5         3
1,5,5,5           5
1,1,1,1                    2.2.3.5 = 60

Bons estudos

Answer 2

M (3)= {0,3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54,57,60...}
M (5)= {0,5,10,15,20,25,30,35,40,45,50,55,60...}
M (15)= {0,15,30,45,60...}
M (20)= {0,20,40,60..)

MMC (3,5,15,20)= 60
