Best Answer

Umm, Lowest Common Multiple and Greatest Common Factor. Not Lowest Common Factor (Which would always be 1 no matter what the numbers are).

If you meant LCM: 126

If you meant GCF: 6

The Least Common Factor of 18 and 24?

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
