Ok an easy question i do not have any primeproduct algorithm going, so i would be interested in a list of primeproducts less than a million that has two as factor?
Can not be that many or?
If not that many would be nice for 10 000 000 and for 100 000 000?
Well if already a million would have couple of 100 i am not that interested in the bigger numbers.
