Two common ways to pay down debt are Debt Snowball and Debt Stacking. A common misconception is that the Debt Snowball is the best way to pay down debt, but really, Debt Stacking is. (This answer assumes your main goal in paying down debt is paying as little and as fast as possible.)
Also, consider doing a balance transfer. This is a way to kick the stone down the road, but it can give a period of relief from having to pay interest, which can be immensely helpful.
