I created a macro that processed through the generated list of numbers in the source input. tested it for 50, 100 and 1000 (was slow)... not sure how large it can go before the performance would degrade completely.
It checks divides each number by the entire list to find a count of any calculations that resulted in a whole number. if count is 0 then it gets left at the end. I had to hard code 1 and 2 to be removed from the results.
