I can convert an expression with the head of Times,for example, `12*12.5*13*13.5*14*14.5` to `{12, 12.5, 13, 13.5, 14, 14.5}` by using the code below：

> ReleaseHold[HoldForm[12*12.5*13*13.5*14*14.5] /. Times -> List]

I have a list which contains a lot of such expressions,here is an example:

> listSample={12*12.5*13*13.5*14*14.5, 12*12.5*13*13.5*14*14.5, 
 12*12.5*13*13.5*14*14.5, 12*12.5*13*13.5*14*14.5, 
 12*12.5*13*13.5*14*14.5, 12*12.5*13*13.5*14*14.5}

I still want to convert all the heads `Times` to `List`,but I failed when tried to Map `HoldForm` to each listItem,because it alway evaluates first.
Here is my code:

> ReleaseHold[HoldForm[#] /. Times -> List]&/@listSample

I want to get this result:

> {{12, 12.5, 13, 13.5, 14, 14.5},{12, 12.5, 13, 13.5, 14, 14.5},{12, 12.5, 13, 13.5, 14, 14.5},{12, 12.5, 13, 13.5, 14, 14.5},{12, 12.5, 13, 13.5, 14, 14.5},{12, 12.5, 13, 13.5, 14, 14.5}}
