10,800

Step-by-step explanation:

Let the least five digit number be x

Factor of

$12=2\times2\times3\\18=2\times3\times3\\20=2\times2\times5\\25=5\times5$

L.C.M = $2\times2\times3\times3\times5\times5$

         = $900$

$x\times900=10000\\900x=10000\\x=\frac{10000}{900}\\x=11.11(Rounding.off)\\x=12$
