Given numbers are 843, 243, 794, 209

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

Apply this formula for all numbers.

Step1:

LCM(843, 243) = 68283

GCD(843, 243) = ( 843 x 243 ) / 68283

= 843 / 243

= 843

Step2:

LCM(3, 794) = 2382

GCD(3, 794) = ( 3 x 794 ) / 2382

= 3 / 794

= 3

Step3:

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

= 1 / 209

= 1

So, Greatest Common Divisor of 843, 243, 794, 209 is 1
