If a number is divisible by $12,18,30$. Then it should be a multiple of LCM of 12,15 and 18 .
Now,
$\mathit{L}\mathit{C}\mathit{M}$ of 12,15 and $18=2\times 2\times 3\times 3\times 5=180$
The smallest 5 -digits number is 10000 .
Now, divide it by $180.$
We get a quotient 55 remainder is 100 .
If we add 80 to it then it will be completely divided by 180 with a quotient $56.$
Therefore,
$180*56=10080$
