Given numbers are 685, 387, 545, 425

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

Apply this formula for all numbers.

Step1:

LCM(685, 387) = 265095

GCD(685, 387) = ( 685 x 387 ) / 265095

= 685 / 387

= 685

Step2:

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

= 1 / 545

= 1

Step3:

LCM(1, 425) = 425

GCD(1, 425) = ( 1 x 425 ) / 425

= 1 / 425

= 1

So, Greatest Common Divisor of 685, 387, 545, 425 is 1
