How to formate hidden recovery partitions of Lenovo G510 laptop

I upgraded my Lenovo G510(windows 8.1) to Windows 10 when it was rolled out for free upgrade. Since then I am using Windows 10 (current version 1703) and don't have any attention or need ever to go back to win 8.1 again. My question is:

• How can I format hidden partitions of my laptop to free up space used by those obsolete recovery partitions.
• Which of 5 or 6 hidden partitions should I format for this purpose that are being shown in disk management.

Thanks in advance.
