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.

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
