Answer:

15

8

8

9

6

Step-by-step explanation:

15 and 30

-The common factors of 15 and 30 are 1, 3, 5, and 15. The greatest common factor is 15

16 and 24

-There are 4 common factors of 16 and 24, that are 8, 1, 2, and 4. Therefore, the highest common factor of 16 and 24 is 8

24 and 40

-Factors for 24: 1, 2, 3, 4, 6, 8, 12, and 24. Factors for 40: 1, 2, 4, 5, 8, 10, 20, and 40.

18 and 24

-GCF of 18 and 27 is 9. To calculate the greatest common factor (GCF) of 18 and 27, we need to factor each number (factors of 18 = 1, 2, 3, 6, 9, 18; factors of 27 = 1, 3, 9, 27) and choose the greatest factor that exactly divides both 18 and 27, i.e., 9.

12 and 18
