Question

find the LCM of the following:-
1.x , x+1 ,x+2
2.x squre , x , x+5

Answer 1

1) The LCM of X, X+1, X+2 is just multiplication of these three numbers as there are no common factors. That is - X(X+1)(X+2)

2)The LCM of $x^{2} ,$, X, X+5 is $x^{2} .(x+5)$ 
 Because, X is a common factor between the first two terms. 

Hope this helps.
