LCM And HCF Undersatnding

                                                            LCM and HCF

LCM stands for Lest common multiple.

                    Least ==  smallest                                              Highest = Gratest
                   Common = among number                                  Common = among numbers
                    Multiple =  explained below                                Factors= Divisor

there are two words one is factor and other is multiple.Consider this example 6

we can write 6 like this  3 x 2 = 6

 3 and 2 are factors of 6. It means that 6 is divisible by 2 and 3.

While 6 is multiple of 3 and 2.It means that 6 comes in the table of 3 and 2 so we can get 6 if we multiply 3 and 2
