Answer:
4
Step-by-step explanation:
Step 1 : List the prime factors of each number
8 : 2 x 2 x 2
12 : 2 x 2 x 3
Step 2: Identify the numbers that are common between the two sets of prime factors:
in our case, we see that only "2 x 2" shows up in both lines, hence 2 x 2 is the GCF.
2 x 2 = 4
Hence the GCF is 4
