Explicație pas cu pas:
72 | 2
36 | 2
18 | 2
9 | 3
3 | 3
1 | - ⇒ 72 = 2³ × 3²
320 | 2
160 | 2
80 | 2
40 | 2
20 | 2
10 | 2
5 | 5
1 | - ⇒ 320 = 2⁶ × 5
280 | 2
140 | 2
70 | 2
35 | 7
5 | 5
1 | - ⇒ 280 = 2³ × 7 × 5
c.m.m.d.c = 2³ = 8
c.m.m.m.c = 2⁶ × 3² × 5 × 7
c.m.m.m.c = 64 × 9 × 35
c.m.m.m.c = 576 × 35
c.m.m.m.c = 20160.
