The list of prime factors of all numbers are
Prime factors of 770 are 2 x 5 x 7 x 11
Prime factors of 556 are 2 x 2 x 139
Prime factors of 866 are 2 x 433
Prime factors of 765 are 3 x 3 x 5 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 770, 556, 866, 765
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 556) = 214060
GCD(770, 556) = ( 770 x 556 ) / 214060
= 770 / 556
= 770
Step2:
LCM(2, 866) = 866
GCD(2, 866) = ( 2 x 866 ) / 866
= 2 / 866
= 2
Step3:
LCM(2, 765) = 1530
GCD(2, 765) = ( 2 x 765 ) / 1530
= 2 / 765
= 2
So, Greatest Common Divisor of 770, 556, 866, 765 is 1
