Question

144 and 198 linear combination​

Answer 1

b = 198; a = 144

b = a*q+r

198 = 144 * 1 + 54

144 = 54 * 2 + 36

54 = 36 * 1 + 18

36 = 18 * 2 + 0

HCF = 18

Linear pair combination,

18 = 54 - 36 * 1

    = 54 - ( 144 - 54 * 2)

    = 54 - 144 + 54 * 2

     = 54 * 3 - 144

     = 3( 198 - 144 * 1) - 144

     = 198 * 3 - 144 * 3 - 144

     = 198 * 3 - 144 * 4

HI, hope it is clear!
