Given numbers are 168, 819, 928, 309

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

Apply this formula for all numbers.

Step1:

LCM(168, 819) = 6552

GCD(168, 819) = ( 168 x 819 ) / 6552

= 168 / 819

= 168

Step2:

LCM(21, 928) = 19488

GCD(21, 928) = ( 21 x 928 ) / 19488

= 21 / 928

= 21

Step3:

LCM(1, 309) = 309

GCD(1, 309) = ( 1 x 309 ) / 309

= 1 / 309

= 1

So, Greatest Common Divisor of 168, 819, 928, 309 is 1
