Given numbers are 685, 389, 609, 526

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

Apply this formula for all numbers.

Step1:

LCM(685, 389) = 266465

GCD(685, 389) = ( 685 x 389 ) / 266465

= 685 / 389

= 685

Step2:

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

= 1 / 609

= 1

Step3:

LCM(1, 526) = 526

GCD(1, 526) = ( 1 x 526 ) / 526

= 1 / 526

= 1

So, Greatest Common Divisor of 685, 389, 609, 526 is 1
