Answer:

1. 10 and 20

Solutions:

Finding the GCF

We must list first their factors.

10 = 1, 2, 5, and 10

20 = 1, 2, 4, 5, 10, and 20

Then, seek for the highest number that is common to both numbers. We can see that 10 is the highest number, so 10 is our GCF.

Finding the LCM

List first their multiples.

10 = 10, 20, 30, 40, 50

20 = 20, 40, 60, 80, 100

Then, seek for the lowest number that is common to both numbers. We can see that 20 is the lowest number, so 20 is our LCM.

GCF: 10

LCM: 20

2. 4 and 12

Solutions:

Finding the GCF

We must list first their factors.

4 = 1, 2, 4

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

Then, seek for the highest number that is common to both numbers. We can see that 4 is the highest number, so 4 is our GCF.

Finding the LCM

List first their multiples.

4 = 4, 8, 12, 16, 20, 24

12 = 12, 24, 36, 48, 60

Then, seek for the lowest number that is common to both numbers. We can see that 12 is the lowest number, so 12 is our LCM.

GCF: 4

LCM: 12

3. 10 and 15

Solutions:

Finding the GCF

We must list first their factors.

10 = 1, 2, 5, and 10

15 = 1, 2, 3, 5, 15

Then, seek for the highest number that is common to both numbers. We can see that 5 is the highest number, so 5 is our GCF.

Finding the LCM

List first their multiples.

10 = 10, 20, 30, 40, 50

15 = 15, 30, 45, 60, 75

Then, seek for the lowest number that is common to both numbers. We can see that 30 is the lowest number, so 30 is our LCM.

GCF: 5

LCM: 30

4. 6 and 24

Solutions:

Finding the GCF

We must list first their factors.

6 = 1, 2, 3, 6

24 = 1, 2, 4, 6, 12, 24

Then, seek for the highest number that is common to both numbers. We can see that 6 is the highest number, so 6 is our GCF.

Finding the LCM

List first their multiples.

6 = 6, 12, 18, 24, 30, 36

24 = 24, 48, 72

Then, seek for the lowest number that is common to both numbers. We can see that 24 is the lowest number, so 24 is our LCM.

GCF: 6

LCM: 24

5. 25 and 30

Solutions:

Finding the GCF

We must list first their factors.

25 = 1, 5, 25

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

Then, seek for the highest number that is common to both numbers. We can see that 5 is the highest number, so 5 is our GCF.

Finding the LCM

List first their multiples.

25 = 25, 50, 75, 100, 125, 150

30 = 30, 60, 90, 120, 150

Then, seek for the lowest number that is common to both numbers. We can see that 150 is the lowest number, so 150 is our LCM.

GCF: 5

LCM: 150
