Question

BCNN(8,6,9)

BCNN(9,15)

ƯCLN(9,15)

BC(8,9,6)

ƯC(9,150

Answer 1

\(BCNN\left(8,6,9\right)=72\\ BCNN\left(9,15\right)=45\\ ƯCLN\left(9,15\right)=3\\ BC\left(8,9,6\right)=B\left(72\right)=\left\{0;72;144;216;...\right\}\\ ƯC\left(9,150\right)=Ư\left(3\right)=\left\{-3;-1;1;3\right\}\)

Answer 2

BCNN(8,6,9)=72

BCNN(9,15)=45

ƯCLN(9,15)=3

BCNN(8,9,6)=0;72;144;216;...

ƯCLN(9,150)=1;3
