Given numbers are 693, 539, 686, 809

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

Apply this formula for all numbers.

Step1:

LCM(693, 539) = 4851

GCD(693, 539) = ( 693 x 539 ) / 4851

= 693 / 539

= 693

Step2:

LCM(77, 686) = 7546

GCD(77, 686) = ( 77 x 686 ) / 7546

= 77 / 686

= 77

Step3:

LCM(7, 809) = 5663

GCD(7, 809) = ( 7 x 809 ) / 5663

= 7 / 809

= 7

So, Greatest Common Divisor of 693, 539, 686, 809 is 1
