Verified by GMS
Given numbers are 43,91 and 183.
Subtract smallest number from both the highest numbers.
we have three cases :
183>43 ; 183>91 and 91>43
183−43=140
183−91=92 and
91−43=48
Now , we have three new numbers : 140,48 and 92
For HCF of 140,48 and 92 using prime factorization method, we get
HCF (140,48 and 92)=4
the highest number that divide 183,91 and 43 and leave the same remainder is 4.
