Question

Aflati cel mai mare divizor comun si cel mai mic multiplu comun al numerelor : 6 si 12, 6,12si 18,30,40 si 50, 63,72 si 81;

Answer 1

6=2x3
12=2²x3
c.m.m.dc=2
c.m.m.m.c=2²x3=12

6,12 si 18
6=2x3
12=2²x3
18=3²x2
c.m.m.d.c=2x3=6
c.m.m.m.c=2²x3²=36

30=3x2x5
40=2³x5
50=5²x2
c.m.m.d.c=5x2=10
c.m.m.m.c=3x2³x5²=600

63=3²x7
72=2³x3²
81=3⁴
c.m.m.d.c=3²=9
c.m.m.m.c=3⁴x2³x7=4536
