Answer 1

Explicație pas cu pas:

a) 180 = 2 x 2 x 3 x 3 x 5

847 = 3 x 3 x 3 x 3 x 3

231 = 3 x 7 x 11

c.m.m.d.c. = 2 x 3 x 3 x 5 = 90

c.m.m.m.c. = 2 x 2 x 3 x 3 x 3 x 3 x 3 x 7 x 11 = 84700

b) 3600 = 2 x 2 x 2 x 2 x 3 x 3 x 5 x 5

4500 = 3 x 3 x 3 x 3 x 5 x 5

320 = 2 x 2 x 2 x 2 x 2 x 5

240 = 2 x 2 x 2 x 2 x 3 x 5

c.m.m.d.c. = 2 x 2 x 2 x 2 x 3 x 5 = 120

c.m.m.m.c. = 2 x 2 x 2 x 2 x 3 x 3 x 3 x 3 x 5 x 5 = 36000
