Common factors in a list

I'm working with a list (vector) that's composed of functions such as 
complex exponentials and Bessel functions.  Some of the functions are common 
to each element of the list.  I'm trying to find a way to do the following:

   {a x, a y, a z}-> a *{x, y, z}

In this expression, a, x, y, z are polynomials, exponentials and/or Bessel 
functions.

So far I haven't had any luck with this.  Does anyone have a simple 
solution?
