GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(876, 865) = 757740
GCD(876, 865) = ( 876 x 865 ) / 757740
= 876 / 865
= 876
Step2:
LCM(1, 686) = 686
GCD(1, 686) = ( 1 x 686 ) / 686
= 1 / 686
= 1
Step3:
LCM(1, 656) = 656
GCD(1, 656) = ( 1 x 656 ) / 656
= 1 / 656
= 1
So, Greatest Common Divisor of 876, 865, 686, 656 is 1
