Given numbers are 685, 285, 823, 474

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

Apply this formula for all numbers.

Step1:

LCM(685, 285) = 39045

GCD(685, 285) = ( 685 x 285 ) / 39045

= 685 / 285

= 685

Step2:

LCM(5, 823) = 4115

GCD(5, 823) = ( 5 x 823 ) / 4115

= 5 / 823

= 5

Step3:

LCM(1, 474) = 474

GCD(1, 474) = ( 1 x 474 ) / 474

= 1 / 474

= 1

So, Greatest Common Divisor of 685, 285, 823, 474 is 1
