No, you do not have to start a factor tree with 2 for an even number. While 2 is always a factor of an even number, you can choose any valid factor pair to begin the tree.
Conditions: The number is even.; The chosen first split is still a valid factor pair.

Yes, starting a factor tree with a different pair of factors will still yield the same prime factors. The final set of prime factors is unique regardless of the initial split.
Conditions: The number being factored is the same.; Each branch is decomposed into valid factor pairs.; The process continues until all leaves are prime.

You can check a prime factorization by multiplying the prime factors back together. If the product equals the original number, the factorization is correct.
Conditions: The factors being multiplied must be the claimed prime factors.; The product must equal the original number exactly.
