Step 1: Identify the prime factors of 96. Now, 96 = 2 × 2 × 2 × 2 × 2 × 3. Step 2: Identify the prime factors of 96. Now, 108 = 2 × 2 × 3 × 3 × 3. Step 3: Gather all prime factors those are common in step 1 and step 2. And they are 2, 2 and 3. Step 4: Multiply all prime factors collected in step 3. And it is 2 × 2 × 3 = 12 Therefore, the GCF of 96 and 108 is 12.
