Given numbers are 685, 530, 709, 297

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

Apply this formula for all numbers.

Step1:

LCM(685, 530) = 72610

GCD(685, 530) = ( 685 x 530 ) / 72610

= 685 / 530

= 685

Step2:

LCM(5, 709) = 3545

GCD(5, 709) = ( 5 x 709 ) / 3545

= 5 / 709

= 5

Step3:

LCM(1, 297) = 297

GCD(1, 297) = ( 1 x 297 ) / 297

= 1 / 297

= 1

So, Greatest Common Divisor of 685, 530, 709, 297 is 1
