Given numbers are 398, 718, 227, 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, 718) = 142882

GCD(398, 718) = ( 398 x 718 ) / 142882

= 398 / 718

= 398

Step2:

LCM(2, 227) = 454

GCD(2, 227) = ( 2 x 227 ) / 454

= 2 / 227

= 2

Step3:

LCM(1, 637) = 637

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

= 1 / 637

= 1

So, Greatest Common Divisor of 398, 718, 227, 637 is 1
