GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(977, 991) = 968207
GCD(977, 991) = ( 977 x 991 ) / 968207
= 977 / 991
= 977
Step2:
LCM(1, 309) = 309
GCD(1, 309) = ( 1 x 309 ) / 309
= 1 / 309
= 1
Step3:
LCM(1, 976) = 976
GCD(1, 976) = ( 1 x 976 ) / 976
= 1 / 976
= 1
So, Greatest Common Divisor of 977, 991, 309, 976 is 1
