Given numbers are 421, 371, 209, 591

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

Apply this formula for all numbers.

Step1:

LCM(421, 371) = 156191

GCD(421, 371) = ( 421 x 371 ) / 156191

= 421 / 371

= 421

Step2:

LCM(1, 209) = 209

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

= 1 / 209

= 1

Step3:

LCM(1, 591) = 591

GCD(1, 591) = ( 1 x 591 ) / 591

= 1 / 591

= 1

So, Greatest Common Divisor of 421, 371, 209, 591 is 1
