a)36,16,48
36 = 4·9 = 2²·3²
16 = 4·4 = 2⁴
48 = 16·3=2⁴·3
se aleg factorii comuni la puterea ceea mai mica
c.m.m.d.c.(36 , 16 ,48) = 2² = 4
b)8,24,36
8 = 2³
24 = 6· 4 = 2 ·3 · 2²= 2³ ·3
36 = 6 · 6 = 2²·3²
c.m.m.d.c (8,24, 36)= 2² = 4
c)15,36,12
15 =3 · 5
36 = 6 · 6 = 2²·3²
12 = 2² ·3
c.m.m.d.c (15, 36, 12)= 3
d)20, 30,40
20 = 2² · 5
30 = 2· 3 · 5
40 = 2³ ·5
c.m.m.d.c (20, 30, 40) = 2
e)126,162,270
126 = 2· 3²· 7
162 = 2 · 3⁴
270= 2 · 3³ · 5
c.m.m.d.c (126, 162, 270) = 2 · 3² = 2 · 9 = 18
f)360,2700,630
360 = 2³ · 3² · 5
630 = 2 · 3² · 5 · 7
2700 = 2² · 3³ · 5²
c.m.m.d.c (360, 2700, 630) = 2 · 3² · 5 = 90.
