    2

    Step-by-step explanation:

    When I find GCF, I like to use the factor tree to do prime facotrization. The prime factorization of 10 is 2 and 5. The prime factorization of 12 is 2,2, and 3. The last step is to selected the prime numbers that are the same.

    10: 2, 5

    12: 2,2,3

    As you can see, 2 is the only number that is in both of the prime factorization so the answer is 2.
