Respuesta:
a.
4 = 2²
32 = 2⁵
40 = 2³ x 5
m.c.m. (4, 32, 40) = 2⁵ x 5 = 32 x 5 = 160
b.
36 = 2² x 3²
72 = 2³ x 3²
60 = 2² x 3 x 5
m.c.m. (36, 72, 60) = 2³ x 3² x 5 = 8 x 9 x 5 = 360
c.
80 = 2⁴ x 5
160 = 2⁵ x 5
100 = 2² x 5²
m.c.m. (80, 160, 100) = 2⁵ x 5² = 32 x 25 = 800
d.
70 = 2 x 5 x 7
140 = 2² x 5 x 7
50 = 2 x 5²
m.c.m. (70, 140, 50) = 2² x 5² x 7 = 4 x 25 x 7 = 700
e.
20 = 2² x 5
50 = 2 x 5²
80 = 2⁴ x 5
m.c.m. (20, 50, 80) = 2⁴ x 5² = 16 x 25 = 400
