Given numbers are 254, 657, 638, 591

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

Apply this formula for all numbers.

Step1:

LCM(254, 657) = 166878

GCD(254, 657) = ( 254 x 657 ) / 166878

= 254 / 657

= 254

Step2:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

Step3:

LCM(1, 591) = 591

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

= 1 / 591

= 1

So, Greatest Common Divisor of 254, 657, 638, 591 is 1
