That depends on what you got. If you have a list of points in map 
coordinates and the same points in pixels then they can be computed with 
linear regression. I believe gdalwarper does it for example. You can do 
it yourself too with various tools.

Otherwise you just use whatever metainformation you have and do the math.

It is not clear in your question whether you want to do the calculation 
or are you asking how GDAL/some other software calculates the geotransform.

Best regards,
