Ah, isn't finding the least common multiple a joyous journey? The LCM of 4x and 3x is simply 12x, my friend. Just like painting a happy little tree, finding the LCM brings harmony and balance to your mathematical landscape.

It is not possible to give a sensible answer to this question. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers (or expressions). You have only one expression in the question: 15xy. Also, if 5x3y is different from 15xy then multiplication is not commutative in whatever set these belong to. In that case it is impossible to find the LCM without information about the rules of "multiplication" in this set.
LCM(12x, 8y) = 24xy.
The LCM is 1320.
√(12x3y3z-2) * √(15xy) = √(180x4y4x-2) = 13.416x2y2z-1 = 13.416(xy)2/z

LCM(5x, 12x) = 60x

LCM(12x, 40y3) = 120xy3
Oh, dude, the Least Common Multiple (LCM) of 36ab and 4b is 36ab. Since 36ab contains both 36 and a, and 4b only has 4 and b, you just take the highest power of each factor. So, yeah, 36ab it is. Easy peasy lemon squeezy.
That will depend on the value of x
