139 is already prime; no factorization required.
Either or both.
You can use either, so technically you don't "need" one or the other. HOWEVER, for large numbers, Euclid's division algorithm is much faster... INCREDIBLY faster. It gets you the result almost immediately, whereas looking for prime factors of large numbers can take you a long, long time.

What is arithmatic
You either can divide the number, or use the factor tree which is prime factorization or just factorization. However I don't know the answer of that, so you might have to figure that out. :D

Currently there are 282 either full or provisional members of Division II.
The reason for repeating an experiment is to either verify or disprove the original finding.
