If the question is in the context of integers and prime factorisation, then it is the number 1.
If the question is about the product of two real numbers, the answer is when both factors are between 0 and 1, or when one of the factors is greater than 1 and the other is negative.

If there are three factors, then one of them being less than 1 does not imply anything about the product of all three and either of the other two factors. For example, 2 = 0.5*1*4 where the first factor is less than 1. The product 2 is less than one of the other factors but bigger than the last.
yes because it is greater than 1
That happens when only one of the two integers is negative.
When one of the numbers is positive and the other is negative.
If the two numbers have no common factors (other than 1), then the LCM is equal to the product of the two numbers. If they have some factors in common, then those factors need only be used once when multiplying, so the LCM will be less than the product of the two numbers.
