How do you find out that a number is prime or composite without checking factors?
There are several advanced methods, but they are all much more complicated than checking for factors. They are, however, efficient for extremely large numbers (such as the 300-digit or so numbers commonly used in cryptography).If you are actually interested in these (more complicated) methods, check the Wikipedia, or do a Google search, on the topic "primality tests".

Yes. To be composite, the first number has at least 2 prime factors, the second number also has at least prime factors; the product of the two will have at least 4 prime factors, so it must be a composite number.
