1 and 3
Common factors of 35 and 49 are 1 and 7
10 1,2,5,10 15 1,3,5, 15
5a ad 7a
The answer depends on what is meant by "fators".
5,5,1,25, just start from the smallest number and multiply then keep going up the numbers.
3, 12/3 = 4, and 42/3 = 14
The factors of 18 are 1, 2, 3, 6, 9, 18. For them to be common, they need to be compared to another set of fators.
