My teacher tells me that to work on fractions, it is useful to master LCM. How can I find it? I have heard of multiples and trees.

FastTamarind948

In my assignment, I am asked to find the LCM and the GCD of the following numbers: 10 and 15.

I know that LCM means least common multiple and GCD means greatest common divisor but I do not know their concrete definition.

Thank you very much for helping me, that will clarify everything
