When looking for factors, try out some small numbers, such as 2, 3, 5, 7. In this case, it is quite obvious that 129 is not divisible by 2. But if you continue trying, you see that it IS divisible by 3. Of course, if you divide 129 by 3, you get the other factor.
1, 2, 3, 5, 6, 10, 15, 30, 43, 86, 129, 215, 258, 430, 645, 1290.
