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.

The common factors of 35 and 70 are the numbers that divide both 35 and 70 without leaving a remainder. The factors of 35 are 1, 5, 7, and 35, while the factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70. The common factors are therefore 1, 5, 7, and 35.
they are 1,2,4,7,14,28
