What is the greatest common factor for 56 64 and 104?

To find the greatest common factor (GCF) of 56, 64, and 104, we first need to find the prime factorization of each number. The prime factorization of 56 is 2^3 * 7, the prime factorization of 64 is 2^6, and the prime factorization of 104 is 2^3 * 13. To find the GCF, we look for the highest power of common prime factors in all the numbers, which is 2^3. Therefore, the greatest common factor for 56, 64, and 104 is 8.
