4. Reducing Fractions Using GCF!
VOCAB:
Factor: the numbers you multiply to get another number
Greatest Common Factor (GCF): of two or more non-zero intergers, is the largest natural number that divides the numbers without a remainder.
Steps to reducing fractions using the gcf!
Trick: FCG
FIRST: List all Factors!
2nd : Underline/bold common factors
3rd : Circle greatest common factor!

5. EXAMPLE: the GCF of 8 and 12 is 4. BUT HOW??
EXAMPLE 1: GCF
EXAMPLE:
the GCF of 8 and 12 is 4.
BUT HOW??
ALSO KNOWN AS: greatest common divisor (gcd) or highest common factor (hcf)
GCF = GCD= HCF
FIRST: List all Factors!
8 = 1 • = 1 • 12
8 = 2 • = 2 • 6
12= 3 • 4
2nd : Underline/bold common factors
8 = 1 • = 1 • 12
8 = 2 • = 2 • 6
12= 3 • 4
3rd : Circle greatest common factor!
8 = 1 • = 1 • 12
8 = 2 • = 2 • 6
12= 3 • 4

6. Now that you know how to find the GCF, its time to REDUCE FRACTIONS!!
EXAMPLE 2 GCF Reducing Fraction
Now that you know how to find the GCF, its time to REDUCE FRACTIONS!!
6/9  Step 1: List all Factors
Step 2: Underline Common factors
Step 3: Circle the GREATEST COMMON FACTOR!
Step 1:
6 = 1 • = 1 • 9
6 = 2 • = 3 • 3
Step 4: DIVIDE THE NUMERATOR AND DENOMINATOR BY THE GCF!!
Step 2:
6 = 1 • = 1 • 9
6 = 2 • = 3 • 3 6 9
/ 3 = 2 3
Step 3:
6 = 1 • = 1 • 9
6 = 2 • = 3 • 3
GCF = 3
