Hillshade coming out totally wrong

Hello, I have a DEM of Spain that I mosaicked together using the Mosaic to new raster tool.  When I try to create a hillshade, it comes out very grainy and inaccurate.  For example, the max height is listed as 254 meters, which is about 2000 meters off.  Also the hillshade itself does not look right, it appears very grainy and small.  I have attached a screenshot of the hillshade.  I feel like it has something to do with the Z-factor field in the hillshade dialog, but I have no idea what to set that to so I leave it as the default value of 1.  Any help would be appreciated.

Thanks
