Question

Me ajudem,eu não compreendo muito a matemática !

Answer 1

   
    
M(9) = {0,9,18,27,36,45,54,63,72,81,90}  
M(2) = {0,2,4,6,8,10, 12, 14, 16,18, 20}  

M(9) e M(2)= { 0, 18}  ==>  2

M(15) = {0,15,30,45,60,75,90,105,120,135,150}  
M(3) = {0,3,6,9,12,15,18,21,24,27,30}  

M(15) e M(3)= {0, 15,30}  ==> 3 

M(4) = {0,4,8,12,16,20,24,28,32,36,40}  
M(8) = {0,8,16,24,32,40,48,56,64,72,80}  

M(4) e M(8)= {0,816,24,32,40} ==> 6
