You can put this solution on YOUR website! does not divide evenly by or by . In fact, it cannot be factored into anything with rational coefficients.
The polynomials and have no factor in common.
Finding a common multiple of and
is like finding a common multiple of and .
Since they do not have any common factors, all you can do is multiply them together, and you get the least common multiple that way.
Depending on what you are asked for, or what you are going to do with that common multiple,
you may want to leave the product as ,
or maybe you would want to actually do the multiplication.
