Given numbers are 957, 339, 261, 643

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

Apply this formula for all numbers.

Step1:

LCM(957, 339) = 108141

GCD(957, 339) = ( 957 x 339 ) / 108141

= 957 / 339

= 957

Step2:

LCM(3, 261) = 261

GCD(3, 261) = ( 3 x 261 ) / 261

= 3 / 261

= 3

Step3:

LCM(3, 643) = 1929

GCD(3, 643) = ( 3 x 643 ) / 1929

= 3 / 643

= 3

So, Greatest Common Divisor of 957, 339, 261, 643 is 1
