Question

How to solve LCM [Least Common Factor] and HCF [ Highest Common Factor], I don't know. Pls help me.

Answer 1

Answer:

lets take 2 numbers for eg:

60 and 72

now, lcm of 60= 2*2*3*5

                      72=2*2*2*3

now, hcf of 60= 2*3*2*5

                    72=2*2*2*3*3*

                         but hcf can be taken of 2 numbers like together

like: common factors of 60 and 72= 2*2*3.

Answer 2

Answer:

firstly divide the no by any least no and then divide it again again untill we don't have 1 then multly all the factors for the LCM

and for HCF do same process and and highest common
