Given numbers are 209, 789, 811, 311

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

Apply this formula for all numbers.

Step1:

LCM(209, 789) = 164901

GCD(209, 789) = ( 209 x 789 ) / 164901

= 209 / 789

= 209

Step2:

LCM(1, 811) = 811

GCD(1, 811) = ( 1 x 811 ) / 811

= 1 / 811

= 1

Step3:

LCM(1, 311) = 311

GCD(1, 311) = ( 1 x 311 ) / 311

= 1 / 311

= 1

So, Greatest Common Divisor of 209, 789, 811, 311 is 1
