Given numbers are 187, 459, 642, 307

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

Apply this formula for all numbers.

Step1:

LCM(187, 459) = 5049

GCD(187, 459) = ( 187 x 459 ) / 5049

= 187 / 459

= 187

Step2:

LCM(17, 642) = 10914

GCD(17, 642) = ( 17 x 642 ) / 10914

= 17 / 642

= 17

Step3:

LCM(1, 307) = 307

GCD(1, 307) = ( 1 x 307 ) / 307

= 1 / 307

= 1

So, Greatest Common Divisor of 187, 459, 642, 307 is 1
