Given numbers are 171, 189, 306, 277

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

Apply this formula for all numbers.

Step1:

LCM(171, 189) = 3591

GCD(171, 189) = ( 171 x 189 ) / 3591

= 171 / 189

= 171

Step2:

LCM(9, 306) = 306

GCD(9, 306) = ( 9 x 306 ) / 306

= 9 / 306

= 9

Step3:

LCM(9, 277) = 2493

GCD(9, 277) = ( 9 x 277 ) / 2493

= 9 / 277

= 9

So, Greatest Common Divisor of 171, 189, 306, 277 is 1
