Mathematics Notes for 9th Class Exercise 6.2

“Math” a compulsory subject for 9th class Science students. and Mathematics Notes for 9th Class Exercise 6.2 or Math Notes Class 9 English Medium (Science Group) included in this book.

The Question is How to Finding H.C.F. ? that is Good and knowledgeable Question, lets try to discuss with solution of problems.
We can find H. C. F. of given expressions by the following two methods.
(i) H.C.F By Factorization (ii) H.C.F By Division
Sometimes it is difficult to find factors of given expressions. In that case, method of division can be used to find H. C. F. We consider some examples to explain these two methods.
(i) H.C.F. by Factorization
