Given numbers are 389, 289, 189, 419

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

Apply this formula for all numbers.

Step1:

LCM(389, 289) = 112421

GCD(389, 289) = ( 389 x 289 ) / 112421

= 389 / 289

= 389

Step2:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

Step3:

LCM(1, 419) = 419

GCD(1, 419) = ( 1 x 419 ) / 419

= 1 / 419

= 1

So, Greatest Common Divisor of 389, 289, 189, 419 is 1
