The operations performed in Gaussian elimination are equivalent multiplying by matrices on the left side.

You can see this in the first example here: http://www.cs.cornell.edu/~bindel/class/cs3220-s12/notes/lec07.pdf

Knowing which matrices you multiplied [math]A[/math] by during row reduction can actually be quite useful and efficient for other tasks involving [math]A[/math]. So, no, other methods (with >>9657885 corectly mentioned are equivalent to Gaussian elimination) are not any faster in most cases.
