Given numbers are 475, 238, 251, 643

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

Apply this formula for all numbers.

Step1:

LCM(475, 238) = 113050

GCD(475, 238) = ( 475 x 238 ) / 113050

= 475 / 238

= 475

Step2:

LCM(1, 251) = 251

GCD(1, 251) = ( 1 x 251 ) / 251

= 1 / 251

= 1

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 475, 238, 251, 643 is 1
