a) 654=2*3*109
1058=2*23^2
384=2^7*3
c.m.m.m.c=2^7*3*109*23^2=22.141.824
b) 975=3*5^2*13
648=2^2*3^4
732=2^2*3*61
c.m.m.m.c=2^2*3^4*5^2*13*61=6.423.300
c) 25=5^2
60=2^2*3*5
50=2*5^2
100=2^2*5^2
c.m.m.m.c=2^2*3*5^2=300
d) 40=2^3*5
160=2^5*5
320=2^6*5
64 = 2^6
si inca o data 160????
c.m.m.m.c=2^6*5=320
e) 15=3*5
20=2^2*5
180=2^2*3^2*5
60=2^2*3*5
c.m.m.m.c=2^2*3^2*5=180
