Did you have problems choosing a grid?

Question

Adaptive design

Friends, hello. I'm going crazy with the choice of grid, if anyone is not too lazy, maybe you will advise something.
There is a site 1280 px wide.
3 types of pages: with a right sidebar, with a left sidebar, with two sidebars (nothing can be removed)
Right sidebar 240-300 px in width, left 210-240 px. At the same time, the number of columns between sidebars should be a multiple of 3 or 4.
The total number of columns is not fundamental, just to fit everything)
I thought that the task was trivial, but only superheroes can do it with all the restrictions. Please help the club
