hope it will help u

Answer 2

Answer:

(i) divide 6 from 12,25,30 if any of them can'nt divided than leave it . you willget 2,25,5

(ii) divide 5 from 2,25,5 leave if any of them can'nt be divided. You will get 2,5,1 .

(iii) divide the number from 5 you will get 2,1,1

(iv) at last divide the number from 2 .you will get 1,1,1

(v) Then HCF Will be 6×5×2×2×1

=30×4

=120

one more thing do HCF In descending order

and LCM in ascending order

and divide the number until it end to 1 if it doesn't end to 1 then leave it (Don't write it in Decimal form )
