m(8) = 0,8,24,32,40,48,56,64,72,80,88.96,104.......
b)m(6) = 0,6,12,18,24,30,36,42,48,54,60,66,72,78,84,90,.....
c) m(12) = 012,24,36,48,60,72,84,96,108,.......
d)m (16 ) = 0,16,32,48,64,80,96,112,,,,........
e)m (10 ) = 0,10,20,30,40,50,60,70,80,90,100,110,120,........
f)m (18 ) = 0,18,36,54,72,90,108,126,144,162,180,.......
