Given numbers are 234, 189, 647, 311

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

Apply this formula for all numbers.

Step1:

LCM(234, 189) = 4914

GCD(234, 189) = ( 234 x 189 ) / 4914

= 234 / 189

= 234

Step2:

LCM(9, 647) = 5823

GCD(9, 647) = ( 9 x 647 ) / 5823

= 9 / 647

= 9

Step3:

LCM(1, 311) = 311

GCD(1, 311) = ( 1 x 311 ) / 311

= 1 / 311

= 1

So, Greatest Common Divisor of 234, 189, 647, 311 is 1
