Hello BinayGhosh,

If you only formatted your device then yes you can use the same product key for activation. Also, re-activation should be automatic if Windows was previously activated on your device:

However, if you made a major hardware change on your device, it will depend if your original license is a retail or OEM. If the Windows came pre-installed on your device then it's an OEM which is not transferable.

You can also review this article on how to activate your device after a hardware change:
