Given numbers are 685, 545, 745, 342

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

Apply this formula for all numbers.

Step1:

LCM(685, 545) = 74665

GCD(685, 545) = ( 685 x 545 ) / 74665

= 685 / 545

= 685

Step2:

LCM(5, 745) = 745

GCD(5, 745) = ( 5 x 745 ) / 745

= 5 / 745

= 5

Step3:

LCM(5, 342) = 1710

GCD(5, 342) = ( 5 x 342 ) / 1710

= 5 / 342

= 5

So, Greatest Common Divisor of 685, 545, 745, 342 is 1
