8;12 Greatest common factor what is the answer

Answer 1

4

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
