Which student loan to payoff first?

As the title states Im seeking advice on which of my student loans to payoff first. I have four in question $15,109 @ 6.84% 16,344$ @ 6.31% 5,928$ @ 7% 5,586$ @ 7.6%

I have several others but they are sub 5% in small amounts so I’m not worried about them for now. My main question with these four is it better to pay the highest interest but smaller dollar amount first or the high dollar first? Or pay down higher dollars until equaled out with the highest interest and then switch?
