Given numbers are 196, 638, 291, 289

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

Apply this formula for all numbers.

Step1:

LCM(196, 638) = 62524

GCD(196, 638) = ( 196 x 638 ) / 62524

= 196 / 638

= 196

Step2:

LCM(2, 291) = 582

GCD(2, 291) = ( 2 x 291 ) / 582

= 2 / 291

= 2

Step3:

LCM(1, 289) = 289

GCD(1, 289) = ( 1 x 289 ) / 289

= 1 / 289

= 1

So, Greatest Common Divisor of 196, 638, 291, 289 is 1
