Given numbers are 257, 421, 819, 333

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

Apply this formula for all numbers.

Step1:

LCM(257, 421) = 108197

GCD(257, 421) = ( 257 x 421 ) / 108197

= 257 / 421

= 257

Step2:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

Step3:

LCM(1, 333) = 333

GCD(1, 333) = ( 1 x 333 ) / 333

= 1 / 333

= 1

So, Greatest Common Divisor of 257, 421, 819, 333 is 1
