Given numbers are 197, 631, 474, 128

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

Apply this formula for all numbers.

Step1:

LCM(197, 631) = 124307

GCD(197, 631) = ( 197 x 631 ) / 124307

= 197 / 631

= 197

Step2:

LCM(1, 474) = 474

GCD(1, 474) = ( 1 x 474 ) / 474

= 1 / 474

= 1

Step3:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 197, 631, 474, 128 is 1
