Regulating Greater Voltage

I do not currently have any way of trying this without LM317 regulators, and cannot seem to find an answer anywhere.

Its a question of whether or not connecting together a set of regulators like LM317 in a series type configuration will have an effect of increasing the maximum voltage limit able to be regulated. Will such a configuration result in this happening?

Hello,

What will be the input voltage?
What will be the output voltage?
To reduce the voltage on a regulator, you can use a second regulator that will drop the preregulation:

This is taken from an old national datasheet.
