6 is the greatest common factor. 1 is always the least common factor, I am pretty sure you mean the GCF, not the LCF. Look at factors of 18. 18 itself is not a factor of 24, neither is 9 the next factor, but 6 is a factor of both. Nobody really cares about Least common factors, since it is always the same. There is least common multiple? In case you want the LCM, the least common multiple of two numbers is the product divided by the GCF, so is 18 * 24 / 6 = 72

The GCF is 6. The LCM is 72.

The least common factor of any set of positive integers is 1. The greatest common multiple is an infinite amount and not very practical.

The least common factor is: 1
