Bom dia
a)
mmc(18,36,80)
18 = 2*3^2
36 = 2^2*3^2
90 = 2*3^2*5
mmc = 2^2*3^2*5 = 180
b)
mmc(100,60,40)
100 = 2^2*5^2
60 = 2^2*3*5
40 = 2^3*5
mmc = 2^3*3*5^2 = 600
c)
mdc(18,24,48)
18 = 2*3^2
24 = 2^3*3
48 = 2^4*3
mdc = 2*3 = 6
d)
mdc(20,19,9) = 1
a)
mmc(18,36,80)
18 = 2*3^2
36 = 2^2*3^2
90 = 2*3^2*5
mmc = 2^2*3^2*5 = 180
b)
mmc(100,60,40)
100 = 2^2*5^2
60 = 2^2*3*5
40 = 2^3*5
mmc = 2^3*3*5^2 = 600
c)
mdc(18,24,48)
18 = 2*3^2
24 = 2^3*3
48 = 2^4*3
mdc = 2*3 = 6
d)
mdc(20,19,9) = 1
