GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(657, 126) = 9198
GCD(657, 126) = ( 657 x 126 ) / 9198
= 657 / 126
= 657
Step2:
LCM(9, 317) = 2853
GCD(9, 317) = ( 9 x 317 ) / 2853
= 9 / 317
= 9
Step3:
LCM(1, 949) = 949
GCD(1, 949) = ( 1 x 949 ) / 949
= 1 / 949
= 1
So, Greatest Common Divisor of 657, 126, 317, 949 is 1
