Question

Determinati:
a) (4,6)=
b)(18,12)=
c)[6,9]=
d)[20,30]=
Sa imi aratati cum ati ajuns la rezultat :))))

Answer 1

a) 4=2 la 2 6=2×3 (4,6)=2 b) 18=3 la 2 × 2 12=3× 2 la 2 (18,12)=3×2=6 c) 6=3×2 9=3 la 3 [6,9]=3 la 3 ×2=18 d) 20=5×2 la 2 30=3×2×5 [20,30]=5×2 la 2×3=60 Sper ca te-am ajutat!

Answer 2

a) (4,6)⇔4=2² ;6=2×3}Se iau toti factorii primi comuni,la puterile cele mai mici
c.m.m.d.c (4,6)=2
b) (18,12)⇔18=2×3² ;12=2²×3
c.m.m.d.c (18,12)=2×3=6
c) [6,9]⇔6=2×3; 9=3² }Se iau toti factorii primi,la puterile cele mai mari
c.m.m.m.c [6,9]=2×3²=18
d)[20,30]⇔20=2²×5;30=2×3×5
c.m.m.m.c [20,30]=2²×3×5=60
