Question

Calcule na decomposição do mmc de cada número:
a)mmc(18,30)
b)mmc(12,66)
c)mmc(45,60)
d)mmc(30,50)

Answer 1

a) 
18, 30 | 2
  9, 15 | 3
   3,  5 | 3
   1,  5 | 5
    1,  1
mmc(18,30) = 2.3.3.5 = 90

b) 
12, 66 | 2
  6, 33 | 2
  3, 33 | 3
  1, 11 | 11
  1,   1
mmc(12,66) = 2.2.3.11 = 132

c)
45, 60 | 2
45, 30 | 2
45, 15 | 3
15,   5 | 3
  5,   5 | 5
  1,   1
mmc(45,60) = 2.2.3.3.5 = 180

d)
30, 50 | 2
15, 25 | 3
  5, 25 | 5
  1,   5 | 5
  1,   1
mmc(30,50) = 150
