calculati c.m.m.m.c al numerelor : a) 225 si -75 b) -234si 54 c) 33,-48si-396 ?????.

Răspuns :

Simulink
a) [225,-75]=[225,75]
[tex]225=3^2*5^2 \\ 75=3*5^2\\ cmmmc= 3^2*5^2=225[/tex]

b)[-234,54]=[234,54]
[tex]234=2*3^2*13\\ 54=2*3^3\\ cmmmc=2*3^3*13=2*27*13=702[/tex]

c)[33,48,-396]=[33,48,396]
[tex]33=3*11\\ 48=2^4*3\\ 396=2^2*3^2*11\\ cmmmc=2^4*3^2*11=16*9*11=1584[/tex]
