Given numbers are 685, 957, 302, 691

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

Apply this formula for all numbers.

Step1:

LCM(685, 957) = 655545

GCD(685, 957) = ( 685 x 957 ) / 655545

= 685 / 957

= 685

Step2:

LCM(1, 302) = 302

GCD(1, 302) = ( 1 x 302 ) / 302

= 1 / 302

= 1

Step3:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

So, Greatest Common Divisor of 685, 957, 302, 691 is 1
