from the Rashtrapati Bhawan along the Rajpath in New Delhi. Several regiments of the army,

navy, and air force, along with their bands, march to India Gate. The parade is presided over by the

President of India, who is the Commander-in-Chief of the Indian Armed Forces. As he unfurls the

to find the HCF of 657 and 963, we will use Euclid's division Lemma,

963 = 657*1+306

since the remainder is not equal to zero, we will again apply Euclid's division Lemma

657 = 306*2+ 45

306 = 45*6 + 36

45 = 36*1 +9

36 = 9*4 + 0

now we get remainder as 0 , thus the HCF of 963 and 657 is 9.

9 = 657 x + 963 x -15

1620 x = 9+15 = 24

x = 24 / 1620 = 2/135

hope this helps you.
