Question about Reverb Effect


Why does Compfilter require these sets of number in Comptuning? 
1116, 1188, 1277, 1356, 1422, 1491, 1557, 1617 ? 

I try to change this set of number to another numbers , and sound so weird ...

I just want to know why Reverb must use these sets of number ...

Ps.I've try to search it in google before ... and look like every reverb effect's code use these nubmers too
