Given numbers are 198, 422, 379, 638

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

Apply this formula for all numbers.

Step1:

LCM(198, 422) = 41778

GCD(198, 422) = ( 198 x 422 ) / 41778

= 198 / 422

= 198

Step2:

LCM(2, 379) = 758

GCD(2, 379) = ( 2 x 379 ) / 758

= 2 / 379

= 2

Step3:

LCM(1, 638) = 638

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

= 1 / 638

= 1

So, Greatest Common Divisor of 198, 422, 379, 638 is 1
