In one room there are certain cats and rats.
Count of rats is 999919.
Cats started eating the rats.
Each cat had the same number of rats as the other cats.

Also the count of cats is more than the number of rats they had

Now the question is how many cats are there in the room and how many rats each cat had?

PS: Mind you there is more than 1 cat and each cat had more than 1 rat.

Some time ago I had a post with a title Lyran III inhabitants ... and with those prime numbers on hand, it is not difficult to do the factorization stuff in excel.
