"Welcome to Numbersville, a lively town where numbers come alive! Streets shaped like addition and subtraction signs, houses that look like math symbols, and friendly citizens who love solving problems. But when numbers go out of order, two heroes are always ready to help.

GCF Guy and LCM Lady!"

"Today, two neighboring towns, Evenville and Oddville, need help. Both towns are planning their annual fireworks festivals, but they want to celebrate together. Their calendars don’t match Evenville celebrates every 2 days, and Oddville every 3 days. When can they celebrate on the same day? 

It’s time for GCF Guy to step in!"

GCF Guy: 
"Let’s find the Greatest Common Factor, or GCF! First, we break down the numbers into their prime factors. 
12 = 2 × 2 × 3 
18 = 2 × 3 × 3 
The common factors are 2 and 3. Multiply them, and the GCF is 6! The fireworks can happen every 6 days."

"The towns cheer as their problem is solved, thanks to GCF Guy!" 

"Meanwhile, Farmer Fraction has a problem. His two fields need watering, but they follow different schedules one every 3 days, the other every 5 days. When will they both need water on the same day? It’s LCM Lady’s turn to help!"
