Answer 2

Let us consider the multiples

$\:\:$

$\:\:$For $3$

$\bold{3 \times 1=3}$

$\bold{3 \times 2=6}$

$\bold{3\times3=9}$

$\bold{3\times4=12}$

$\bold{3\times5=15}$

$\bold{3\times6=18}$

$\bold{3\times7=21}$

$\bold{3\times8=24}$

$\bold{3\times9=27}$

$\:\:$

$\:\:$For $9$

$\bold{9 \times 1=9}$

$\bold{9 \times 2=18}$

$\bold{9\times3=27}$

Hence,$9$ is the least in common between the two.
