Step 1: List the Factors of Each Number
First, list all the factors of both 30 and 54.
- Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30
- Factors of 54: 1, 2, 3, 6, 9, 18, 27, 54
Step 2: Identify the Common Factors
Now, identify the factors that are common to both 30 and 54.
- Common factors: 1, 2, 3, 6
Step 3: Choose the Greatest Common Factor
The largest (or greatest) number in the list of common factors is the GCF.
- The greatest common factor of 30 and 54 is 6.
Final Answer:
The GCF of 30 and 54 is 6.
Why is the GCF Important?
Understanding how to find the GCF helps simplify fractions, solve problems with ratios, and is useful in real-world situations like dividing objects evenly.
Quick Recap:
- Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30
- Factors of 54: 1, 2, 3, 6, 9, 18, 27, 54
- Common factors: 1, 2, 3, 6
- GCF: 6
With these easy steps, you can find the GCF of any two numbers.
