Equilibrium Constant K

One possible way of removing NO from the exhaust of a petrol engine is to cause it to react with CO in the presence of a suitable catalyst. 2NO(g) + 2CO(g) → N2(g) + 2CO2(g). At 258 °C, this reaction has Kc=2.9·1059. What is Kp at 258 °C?

The answer is 6.65 x 10^57, PLEASE show your solution steps by steps, and let me know how to do it clearly, thanks a lot!!
