What is the greatest common factor 16 and 104?

Answer 1

First list the factors of 16:1,2,4,8,16. Start with the largest factor (16) and see if it is also a factor of 104 by dividing 104 by 16. When you do you get 6.5, so it is not a factor. So try 8, and when you do you get 13. So 8 is the largest factor of 16 and 104.
