Given numbers are 398, 199, 307, 637

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

Apply this formula for all numbers.

Step1:

LCM(398, 199) = 398

GCD(398, 199) = ( 398 x 199 ) / 398

= 398 / 199

= 398

Step2:

LCM(199, 307) = 61093

GCD(199, 307) = ( 199 x 307 ) / 61093

= 199 / 307

= 199

Step3:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1

So, Greatest Common Divisor of 398, 199, 307, 637 is 1
