Problem understanding 359C Solution

Revision en1, by VeryGoodVeryGood, 2020-08-03 00:20:22

Hi CodeForces, I've been trying to solve this problem for a long time now but really don't get anything about it. I have read the editorial but I can't seem to understand what author means by saying cnt is multiple of x. How does that help solving the problem, could somebody provide an example of how it works or a better explanation. Thanks and sorry if this question is a bit dumb.
