Given numbers are 317, 257, 791, 309
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(317, 257) = 81469
GCD(317, 257) = ( 317 x 257 ) / 81469
= 317 / 257
= 317
Step2:
LCM(1, 791) = 791
GCD(1, 791) = ( 1 x 791 ) / 791
= 1 / 791
= 1
Step3:
LCM(1, 309) = 309
GCD(1, 309) = ( 1 x 309 ) / 309
= 1 / 309
= 1
So, Greatest Common Divisor of 317, 257, 791, 309 is 1
