Given numbers are 189, 711, 494, 643

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

Apply this formula for all numbers.

Step1:

LCM(189, 711) = 14931

GCD(189, 711) = ( 189 x 711 ) / 14931

= 189 / 711

= 189

Step2:

LCM(9, 494) = 4446

GCD(9, 494) = ( 9 x 494 ) / 4446

= 9 / 494

= 9

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 189, 711, 494, 643 is 1
