Given numbers are 257, 408, 651, 339

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

Apply this formula for all numbers.

Step1:

LCM(257, 408) = 104856

GCD(257, 408) = ( 257 x 408 ) / 104856

= 257 / 408

= 257

Step2:

LCM(1, 651) = 651

GCD(1, 651) = ( 1 x 651 ) / 651

= 1 / 651

= 1

Step3:

LCM(1, 339) = 339

GCD(1, 339) = ( 1 x 339 ) / 339

= 1 / 339

= 1

So, Greatest Common Divisor of 257, 408, 651, 339 is 1
