Given numbers are 639, 203, 927, 457

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

Apply this formula for all numbers.

Step1:

LCM(639, 203) = 129717

GCD(639, 203) = ( 639 x 203 ) / 129717

= 639 / 203

= 639

Step2:

LCM(1, 927) = 927

GCD(1, 927) = ( 1 x 927 ) / 927

= 1 / 927

= 1

Step3:

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

= 1 / 457

= 1

So, Greatest Common Divisor of 639, 203, 927, 457 is 1
