Ta có:

\(8=2^3\)

\(12=2^2\cdot3\)

\(15=3\cdot5\)

\(\Rightarrow BCNN\left(8;12;15\right)=2^3\cdot3\cdot5=120\)

\(\Rightarrow BC\left(8;12;15\right)=\left\{0;120;240;360;480;...\right\}\)

Ta có:

`10^9 - 1`

`= (10^3)^3 - 1^3`

`= 1000^3 - 1^3`

`= (1000 - 1)(1000^2 + 1000 . 1 + 1^2)`

`= 999 . (1000^2 + 1000 + 1) \vdots999 (đpcm)`

Vậy: `10^9 - 1 \vdots 999`
