A class LCM has been defined to find the Lowest Common Multiple of two integers.

Some of the data members and member functions are given below:

Class name: LCM
Data members/instance variables:
n1: to store an integer number
n2: to store an integer number
large: integer to store the largest from n1, n2
sm: integer to store the smallest from n1, n2
l: to store LCM of two numbers
Methods/Member functions:
LCM(): default constructor to initialize data members with legal initial values
void accept(): to accept n1 and n2
int getLCM(): returns the LCM of n1 and n2 using the recursive technique
void display(): to print the numbers n1, n2 and LCM

Specify the class LCM giving details of the constructor, void accept(), int getLCM() and void display(). Define a main() function to create an object and call the member functions accordingly to enable the task.
