When the numbers are co-prime, ie have no common factor. Simplest example is 2 & 3 whose LCM is 6
You need at least two numbers to find an LCM. If that's 5 and 3, the LCM is 15.
12 and 15
The set of three numbers whose LCM (Least Common Multiple) is equal to the product of the numbers would be {1, 2, 2}. Here's how it works: LCM(1, 2, 2) = 2, which is also the product of the numbers (1 * 2 * 2 = 4).
