Given numbers are 959, 189, 435, 643

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

Apply this formula for all numbers.

Step1:

LCM(959, 189) = 25893

GCD(959, 189) = ( 959 x 189 ) / 25893

= 959 / 189

= 959

Step2:

LCM(7, 435) = 3045

GCD(7, 435) = ( 7 x 435 ) / 3045

= 7 / 435

= 7

Step3:

LCM(1, 643) = 643

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

= 1 / 643

= 1

So, Greatest Common Divisor of 959, 189, 435, 643 is 1
