If i have a small sum of money and I want to use it to pay off some credit, what would be the best option?

I have three credit cards I need to pay off, 500, 1300, and 3450. I have about 1000 dollars to put towards paying off some debt. would it be better to completely pay off the 500 one and then use the leftover sum for one of the others? or put all of it into the biggest debt? or put even amounts into all three?... show more I have three credit cards I need to pay off, 500, 1300, and 3450.
