This does not work when one of the numbers is negative.
No. Factors go into numbers, numbers go into multiples.
If the GCF of a given pair of numbers is 1, the LCM will be equal to their product. If the GCF is greater than 1, the LCM will be less than their product. Or, stated another way, if the two numbers have no common prime factors, their LCM will be their product.
Two or more whole numbers are required to determine their least common multiple.
The LCM of one number is itself, because LCM stands for least common multiple, it usually (in fact almost always) deals with two or more numbers.
Yes.
There is always an LCM. This one is 15,953.
The LCM of two numbers is sometimes the product of the two numbers.
The HCF is always a factor of the LCM of two numbers. The HCF is a factor of both the numbers which are factors of their LCM. Thus the HCF is also a factor of the LCM of the two numbers.
Sometimes, not always.
If the two numbers have no common factors other than 1, the LCM will be their product. If there are other common factors, the LCM will be less.
If their GCF is 1, their LCM is their product. If their GCF is greater than 1, their LCM is less than their product.
Yes.
Not always. The product of two numbers will always be a common multiple, but it will not always be least. The product of 4 and 9 is 36. The LCM of 4 and 9 is 36. The product of 4 and 8 is 32. The LCM of 4 and 8 is 16.

If they have no common factors other than 1.
