Question

BC_(40,60)

Answer 1

\(B\left(40\right)=\left\{0;40;80;120;160;...\right\}\)

\(B\left(60\right)=\left\{0;60;120;180;240;...\right\}\)

\(BC\left(40;60\right)=\left\{0;120;240;480;960;...\right\}\)

CHUC bn hoc tot!

Answer 2

Có: 40 = 2³.5

      60 = 2².3.5

nên BCNN (40, 60)=2³.3.5=120

\(\Rightarrow\)BC (40, 60)= 0, 120, 240, 360, 480, 600....
