Given numbers are 806, 342, 128, 685

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

Apply this formula for all numbers.

Step1:

LCM(806, 342) = 137826

GCD(806, 342) = ( 806 x 342 ) / 137826

= 806 / 342

= 806

Step2:

LCM(2, 128) = 128

GCD(2, 128) = ( 2 x 128 ) / 128

= 2 / 128

= 2

Step3:

LCM(2, 685) = 1370

GCD(2, 685) = ( 2 x 685 ) / 1370

= 2 / 685

= 2

So, Greatest Common Divisor of 806, 342, 128, 685 is 1
