Answer 1

Answer:

2and 3

Step-by-step explanation:

4= 2*2

7=7*1

8=2*2*2

9=3*3

13=13*1

39=13*3

666=2*3*111

So the common are 2and3

Answer 2

Answer:

To find common factors of more than two numbers, go to the GCF ... For example, the factors of 8 are 1, 2 , 4 and 8 . ... 13. 13 - 6 = 7. Great! We obtained the number divisible by 7, so it ... Factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72.
