1. MetalPen

For this you need to find the LCM; lowest common multiple.

2. MetalPen

15.

15. MetalPen

Here I used 2, 8, and 12

16. MetalPen

You decide what number goes into all of the #s your are using, and then divide them all by that.

17. livliv2000

whats 26x3

18. MetalPen

When you are done you multiply all of the numbers on the side and the bottom together.

19. MetalPen

78

20. livliv2000

what is the lcm of 26 4 7

21. MetalPen

Ummmm.

22. livliv2000

how old are you

23. MetalPen

Why, how old do you think I am?

24. livliv2000

20;s

25. MetalPen

Lol

26. MetalPen

Ya know I'm not sure how to get the LCM, but I think you just multiply everything together. Don't hold me on that!

27. MetalPen

And I'm much younger than 20. If I was 20, I'd be a really stupid 20 year old.

28. MetalPen

Yeah. I guess.

29. MetalPen

I'm afraid I shall not.

30. MetalPen

Au revoir.

31. MetalPen

Et non.

33. MetalPen

34. MetalPen

My name is nothing.

35. MetalPen

Goodbye.
