Given numbers are 318, 189, 809, 457

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

Apply this formula for all numbers.

Step1:

LCM(318, 189) = 20034

GCD(318, 189) = ( 318 x 189 ) / 20034

= 318 / 189

= 318

Step2:

LCM(3, 809) = 2427

GCD(3, 809) = ( 3 x 809 ) / 2427

= 3 / 809

= 3

Step3:

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

= 1 / 457

= 1

So, Greatest Common Divisor of 318, 189, 809, 457 is 1
