The GCF is 4.
To find the greatest common factor (GCF) of 12, 60, and 68, we first need to find the prime factorization of each number. The prime factorization of 12 is 2^2 * 3, the prime factorization of 60 is 2^2 * 3 * 5, and the prime factorization of 68 is 2^2 * 17. The GCF is the product of the common prime factors raised to the lowest power, which in this case is 2^2 = 4. Therefore, the greatest common factor of 12, 60, and 68 is 4.
