Given numbers are 685, 488, 689

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

Apply this formula for all numbers.

Step1:

LCM(685, 488) = 334280

GCD(685, 488) = ( 685 x 488 ) / 334280

= 685 / 488

= 685

Step2:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

So, Greatest Common Divisor of 685, 488, 689 is 1
