Given numbers are 206, 317, 393, 641

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

Apply this formula for all numbers.

Step1:

LCM(206, 317) = 65302

GCD(206, 317) = ( 206 x 317 ) / 65302

= 206 / 317

= 206

Step2:

LCM(1, 393) = 393

GCD(1, 393) = ( 1 x 393 ) / 393

= 1 / 393

= 1

Step3:

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

= 1 / 641

= 1

So, Greatest Common Divisor of 206, 317, 393, 641 is 1
