Yes, the greatest common factor of two different prime numbers is always 1
If you construct them correctly, factor trees always work to determine the prime factorization of a number. Once you compare the prime factorizations of two or more numbers, it is relatively easy to find the greatest common factor of them from there.
Always even.
No, but it's always an even number.
