How to Stop Generating Image-sizes?

Hi,
when uploading an image in Media Library, aside from the original file, it generates many other file-versions with variety of sizes.
Currently in my case, it generates 24 more files from a single upload.

How to stop generating some of these files?

Regenerate Thumbnails plugin shows info for registered thumbnail sizes which I don’t know what are for:

column1-1/2: 1140×570 pixels (cropped to fit)
column1-1/3: 1140×380 pixels (cropped to fit)
column1-1/4: 1140×285 pixels (cropped to fit)
column1-2/5: 1140×456 pixels (cropped to fit)
column2-1/1: 570×570 pixels (cropped to fit)
column2-1/4: 570×142 pixels (cropped to fit)
column2-1/2: 570×285 pixels (cropped to fit)
column2-2/3: 570×380 pixels (cropped to fit)
column2-3/5: 570×342 pixels (cropped to fit)
column3-1/1: 380×380 pixels (cropped to fit)
column3-1/3: 380×107 pixels (cropped to fit)
column3-2/5: 380×152 pixels (cropped to fit)
column3-2/3: 380×254 pixels (cropped to fit)
column3-3/4: 380×285 pixels (cropped to fit)
column4-1/1: 285×285 pixels (cropped to fit)
column4-2/3: 285×190 pixels (cropped to fit)
column4-3/4: 285×214 pixels (cropped to fit)

Does somebody know why are these created and how to stop them?
