Can you please show me how to find the common factors of each set of numbers.

1. 1,4,8,32______
2. 1,3,6,12,24_____

To find the common factor of something, you have to post all the factors of each number. For #1 you would do:
1- 1
4- 1, 2, 4
8- 1, 2, 4, 8
32- 1, 2, 4, 8, 16

Obviously the first one is 1.

A easy way to find the common factor of these questions, is simply by seeing the first number. You can see that all of the set of numbers have 1 in it. 1 has no other common factor, and every real number has a factor of 1. So the answer for both of these problems would be one because its the only plausible answer.

I hope this helps :)

1. 1 = 1*1.
4 = 1*2*2
8 = 1*2*2*2.
32 = 1*2*2*2*2*2.
The common factor is 1.

2. 1 = 1*1
3 = 1*3.
6 = 1*2*3.
12 = 1*2*2*3
24 = 1*2*2*2*3.
The common factor is 1.

the commonfactors are 1,and 3.
