Given numbers are 128, 389, 494

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

Apply this formula for all numbers.

Step1:

LCM(128, 389) = 49792

GCD(128, 389) = ( 128 x 389 ) / 49792

= 128 / 389

= 128

Step2:

LCM(1, 494) = 494

GCD(1, 494) = ( 1 x 494 ) / 494

= 1 / 494

= 1

So, Greatest Common Divisor of 128, 389, 494 is 1
