Given numbers are 685, 397, 605, 652

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

Apply this formula for all numbers.

Step1:

LCM(685, 397) = 271945

GCD(685, 397) = ( 685 x 397 ) / 271945

= 685 / 397

= 685

Step2:

LCM(1, 605) = 605

GCD(1, 605) = ( 1 x 605 ) / 605

= 1 / 605

= 1

Step3:

LCM(1, 652) = 652

GCD(1, 652) = ( 1 x 652 ) / 652

= 1 / 652

= 1

So, Greatest Common Divisor of 685, 397, 605, 652 is 1
