The GCF is 7.
To find the greatest common factor (GCF) of 336 and 630, we first need to find the prime factorization of each number. The prime factorization of 336 is 2^4 * 3 * 7 and the prime factorization of 630 is 2 * 3^2 * 5 * 7. To find the GCF, we take the highest power of each common prime factor, which is 2^1 * 3^1 * 7^1 = 42. Therefore, the greatest common factor of 336 and 630 is 42.
There is no such thing as a greatest common multiple for any numbers. There is a greatest common divisor and that is 2.
