#### Storyboard Text

• Everyone at GVMS got an A on the finals, so I’m gonna throw a huge party! So of course, I need some lemonade. But they sell cups in packs 46, straws in packs of 100 and lemonade in  packs of 16 cups!
• I think I can help!
• I'm the math wizard. I'm here to help you with your problem. All you need to do is find the least common multiple!
• Who are you?
• We'll start with 46. 46 divided by 2 is 23. So we make 2 branches and write 2 and 23 under them. Since 2 and 23 are both prime numbers, write 2 x 23 below.
• 2            23
• 2 x 23
• Wow magic!
• 4                4
• 2 to the 4th power
• 2  2     2  2
• Now let’s do it with 16 and 100! Instead of writing 2x2x2x2, write 2 to the 4th power!
• 10             10
• 5  2             5   2
• 2 to the 2nd power x 5 to the 2nd power
• LCM: 2 to the 4th power x 23 x 5 to the 2nd power= 9200
• Next, we take every final number and multiply them together. Make sure to include the greatest powers of 2 and 5! Finally, divide it by 16, 46 and 100 to see how much of each product you need.
• Thanks, math wizard! Best party EVER!
