A.234,456,789,456

PLEASE ANSWER ME SOON !

Answer :

To find H.C.F. of 234 , 456  , 789 , 456 , we follow these steps :

Step I: First of all find the highest common factor (H.C.F) of any two of the given numbers. 
Lets find H.C.F. ( 456 , 456 ) by long division , As  :

H.C.F.  =  456 

Step II:  Now find the highest common factor (H.C.F) of the third given number and the highest common factor (H.C.F) obtained in Step 1 from first and the second number. 

So we find H.C.F. of 456 , 789  by long division method , As :


Now we follow again step 2 for  3 and 234 , as :


H.C.F. of 234 , 456  , 789 , 456   = 3                                         (  Ans )
