### Project

#### Domain: 
The Number System

#### Standard:
6NS4: Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12.

#### Directions:
1. Read the problem below.
   **Use the hints to help if needed to solve the riddle.**

---
I’m thinking of two numbers. Their greatest common factor is 6. Their least common multiple is 36. One of the numbers is 12. What is the other number?

#### Hints:
1. What are the factors of 12?
2. Can the other number be 3? Why or why not? The number cannot be 3 because the greatest common factor of both of the numbers is 6. (3 cannot have a factor).
3. Can the other number be 6? Why or why not?

**Show your work!**
