Sort Excel rows in numerical order

I working a spread sheet with over 3k of rows that need to be sorted in numerical order for cells C2:G2 for each row, in all 3k of rows while keeping the other data in the row intact.

I tried the sort custom and sort left to right but that would be time consuming for 3K rows

I'm trying to accomplish this the easiest way as i am a beginner.

If you provide the steps to implement I can initiate the steps required. 

any help would be appreciated 

thank you
