Gary made 20 treat bags for his Halloween party. In every 3rd bag he put lollipops, in every 4th bag he put Hershey Kisses and in every 5th bag he put fake eyeballs. How many of the 20 bags have all three items in them? ( By the way this is an LCM problem. I need help asap plz.)

3 - 6 - 9 - 12 - 15 - 18 - 21 - 24 - 27 - 30 - 33 - 36 - 39 - 42 - 45 - 48 - 51 - 54 - 57 - 60

4 - 8 - 12 - 16 - 20 - 24 - 28 - 32 - 36 - 40 - 44 - 48 - 52 - 56 - 60

5 - 10 - 15 - 20 - 25 - 30 - 35 - 40 - 45 - 50 - 55 - 60

SOOOO that means the LCD is 60 c:

( Basically, to find the LCD all you gotta do is count by whichever number is the denominator until they match, in this case, it was 60 )

You can do the rest :D
