What is the greatest common factor on question 2

the GCF is 10, you are correct

Step-by-step explanation:

find the prime factors of each term

1. 2

2. 10

3. 7

4. 3

5. 3

6. 3

7. 3

8. 5

9. 6

10. 4

Step-by-step explanation:

In order to find the greatest common factor (GCF) of two numbers, you need to know what the greatest common factor is. The greatest common factor is the largest positive number, a number can be divided into so to find the greatest common factor you need to list all the integers that the numbers are divisible by and the highest number that both numbers have in common are your GCF.

1.

12, 1, 2, 3, 4, 6, 12

26, 1, 2, 13, 26

GCF = 2

2.

30, 1, 2, 3, 5, 6, 10, 15, 30

40, 1, 2, 4, 5, 8, 10, 20, 40

GCF = 10

3.

35, 1, 5, 7, 35

28, 1, 2, 4, 7, 14, 28

GCF = 7

4.

21, 1, 3, 7, 21

15, 1, 3, 5, 15

GCF = 3

5.

33, 1, 3, 5, 15

15, 1, 3, 11, 33

GCF = 3

6.

27, 1, 3, 9, 27

3, 1, 3

GCF = 3

7.

36, 1, 2, 3, 4, 6, 9, 12, 18, 36

33, 1, 3, 11, 33

GCF = 3

8.

30, 1, 2, 3, 5, 6, 10, 15, 30

5, 1, 5

GCF = 5

9.

30, 1, 2, 3, 5, 6, 10, 15, 30

6, 1, 2, 3, 6

GCF = 6

10.

4, 1, 2, 4

16, 1, 2 ,4, 16

GCF = 4

Hope this helps.
