Given numbers are 340, 394, 20, 459

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

Apply this formula for all numbers.

Step1:

LCM(340, 394) = 66980

GCD(340, 394) = ( 340 x 394 ) / 66980

= 340 / 394

= 340

Step2:

LCM(2, 20) = 20

GCD(2, 20) = ( 2 x 20 ) / 20

= 2 / 20

= 2

Step3:

LCM(2, 459) = 918

GCD(2, 459) = ( 2 x 459 ) / 918

= 2 / 459

= 2

So, Greatest Common Divisor of 340, 394, 20, 459 is 1
