Given numbers are 388, 638, 443, 543

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

Apply this formula for all numbers.

Step1:

LCM(388, 638) = 123772

GCD(388, 638) = ( 388 x 638 ) / 123772

= 388 / 638

= 388

Step2:

LCM(2, 443) = 886

GCD(2, 443) = ( 2 x 443 ) / 886

= 2 / 443

= 2

Step3:

LCM(1, 543) = 543

GCD(1, 543) = ( 1 x 543 ) / 543

= 1 / 543

= 1

So, Greatest Common Divisor of 388, 638, 443, 543 is 1
