The GCF is 2, the LCM is 684.

The GCF you can find by listing all the factors of each number-

36.......38

1..........1

2............2

3...........19

4............32

6

9

12

18

36

Now you want to find the highest possible number on each side (they don't have to lign up). That number is 2. That's your GCF.

LCM is listing all the multiples.

36......38

72.......76

108.....152

144.....190

180.....228

216.....266

.....

Eventually you get to

648.....684

684......722

...............

Those are the first number that they both have in common, therefore it's your answer.

Hope I helped! Give me trust!
