I have doubts about whether you can arrive at this with any certainty. I am assuming the channels are some sort of broadcast channels. Perhaps TV or Radio channels. CCG is ambiguous. It could mean Canadian Coast Guard or perhaps Central Control Government or dozens of other things.
The problem is that you do not know which of 2 channels a particular user will be using at the time of the impression. This means that a user who is common between A and E may see 75,000 impressions on Channel E or may see 250,000 on Channel A. You will need to draw up a list of assumptions to be built into any algorithm, such as - if a user is common to 2 channels that user is assumed to use each channel 50% of the time. This assumption would allow you to eliminate the overlapping users (You would subtract 5 users from Channel A and 5 from Channel E. There may be other issues, particularly with regards to the users with access to 3 or more channels. The above assumption eliminates these. However it may unfairly impact the low usage channels (such as E) because these seem to have disproportionate cross channel overlaps. If you want to give a bit more information, particularly about what the terms "CCG", "Channel", and "Impression" mean, it may be feasible for me or another member (ideally a statistician) to help you further.
