Repede va rogg.

Answer 1

c.m.m.d.c= multiplii comuni celor doua numere(sau cate sunt...)luati la puterea cea mai mica
descompunem numerele
a)360=2la 3x3la2x5
   2700=2la2x3la3x5la2
   630=2x3la2x5x7

c.m.m.d.c=2x3la2x5=2x9x5=90

b)1617=3x7la2x11
7623=3la2x7x11la2
2457=3la3x7x13

c.m.m.d.c=3la2x7=9x7=63

c)7560=2la3x3la3x5x7
153366=2x3x25561
______________________
c.m.m.d.c=2x3=6

d)6699=3x7x11x29
1800=2la3x3la2x5la2
