Given numbers are 685, 392, 717

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

Apply this formula for all numbers.

Step1:

LCM(685, 392) = 268520

GCD(685, 392) = ( 685 x 392 ) / 268520

= 685 / 392

= 685

Step2:

LCM(1, 717) = 717

GCD(1, 717) = ( 1 x 717 ) / 717

= 1 / 717

= 1

So, Greatest Common Divisor of 685, 392, 717 is 1
