Answer 9

lets see...

Answer 10

Yea same for me

Answer 11

The answer is 72. Now I just need to find how to do that by hand...

Answer 12

but I think blexting will explain

Answer 13

24 = 2 * 2 * 2 * 3
36 = 2 * 2 * 3 * 3

Circle numbers they have in common... Put a circle around the 2's and the next 2's and the last 3's .. your lcm is 2 * 2 * 3 (the circled ones) * 2 * 3 the leftover ones.

72

Answer 14

Awesome!

Answer 15

Basically if you count by each number

24,48,72,96,120 etc. ( I am counting by 24's)
36,72,108,144,180, etc. (I am counting by 36's)

What is the first number they both have.... 72

Answer 16

Hmm.... I have to let it soak in Lol i get it so all you really have to do is count each number like 24,48... etc and wait until the numbers have the same answer? But whats with the 2's and stuff like that lol

Answer 17

You can always do the count thing.... you don't have to do the other if you don't want to. it is just quicker.

Answer 18

Yea its seems quicker...... Way easier to... Thanks!
