Given numbers are 398, 427, 643, 430

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

Apply this formula for all numbers.

Step1:

LCM(398, 427) = 169946

GCD(398, 427) = ( 398 x 427 ) / 169946

= 398 / 427

= 398

Step2:

LCM(1, 643) = 643

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

= 1 / 643

= 1

Step3:

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

= 1 / 430

= 1

So, Greatest Common Divisor of 398, 427, 643, 430 is 1
