Given numbers are 126, 889, 686, 545

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(126, 889) = 16002

GCD(126, 889) = ( 126 x 889 ) / 16002

= 126 / 889

= 126

Step2:

LCM(7, 686) = 686

GCD(7, 686) = ( 7 x 686 ) / 686

= 7 / 686

= 7

Step3:

LCM(7, 545) = 3815

GCD(7, 545) = ( 7 x 545 ) / 3815

= 7 / 545

= 7

So, Greatest Common Divisor of 126, 889, 686, 545 is 1
