in ArcMap you can run the tool "mosaic to new raster"
http://desktop.arcgis.com/en/arcmap/10.3/tools/data-management-toolbox/mosaic-to-new-raster.htm
ArcMap also allows you to build virtual mosaics using a mosaic data type or raster catalog.

using GDAL you can build a virtual mosaic too:
$ gdalbuildvrt virtual_mosaic.vrt *.tif
now you can use it directly (as a virtual mosaic) or to push that into a mosaic
$ gdal_translate virtual_mosaic.tif mosaic.tif
