If HCF of 657 and 963 is 657*+963y. find the value of x and y

Answer»

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.

cheers!!

Expansion of (a-b-c)² = ?

Answer»

(a - b - C )^2

= ( a - b - c ) ( a - b - c )

= a ( a - b - c ) - b ( a - b - c ) - c ( a - b - c )

= a ^2 - AB - AC - ab + b ^2 + bc - ac + bc + c 2

= a ^2 + b ^2 + c ^2 - 2ab + 2bc - 2ac

Thetefore,

( a - b - c )^2 = a^2 + b ^2 + c ^2 - 2ab + 2bc - 2ac

Two numbers are in the ratio 5:11. If their HCF is 13 and LCM is 2145, then find the numbers.

Answer»

Let the no are 5x and 11x

we know

LCM × HCF = PRODUCT of two nos.

2145 × 13 = 5x × 11x

27885 / 55 = x^2

507 = x^2


\sqrt{507} = x

22 = x

Hence nos are 5x = 5×22 = 110

11x = 11 × 22 = 242
