Using AM-GM inequality, a+(b/ac)>2(b/c) , b+(c/ab)>2c/a , c+(a/bc)>2a/b, Multiplying these expressions you would automatically get the result.

You're wrong, but the principle is right. $$a+\frac{b}{ac} \geq 2\sqrt{\frac{b}{c}}$$. You just forgot the square root. But when you multiply them together, they cancel anyways, leaving a 1 under the square root.

Actually I entered the square root but it was not displayed in the answer, don't know why.

Weird. Oh well. It works anyways.
