Fill the 5l pitcher, use it to fill the 3l pitcher.
Dump the 3l pitcher out and put what is left in the 5l pitcher into it.
Fill the 5l pitcher and use it to finish filling the 3l pitcher.
You are now left with 4 liters in the larger pitcher.
Pitchers come in all shapes and sizes. A two-quart pitcher would be 1.89 liters.
Pitcher comes in many different sizes. If you are thinking about "a pitcher of beer" in a bar, that usually is 60 US fl oz. I had to highlight "usually" here, as there is no international standard of how big a pitcher should be. I have been to bars that serve a 50oz pitcher, usually those places also serve with a smaller pint, 14 US fl oz versus 16 US fl oz.In general, I would assume a pitcher is 60 US fl oz, which equals to 1.77L.

If the pitchers are 1500 ml, then it takes 20 of them
Water pitchers are available in many sizes, so each will hold the amount of water it is made to hold. It could be a quart, pint, half gallon, or a gallon. Some may be even larger, depending on their intended uses.
