GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 386) = 132398
GCD(686, 386) = ( 686 x 386 ) / 132398
= 686 / 386
= 686
Step2:
LCM(2, 444) = 444
GCD(2, 444) = ( 2 x 444 ) / 444
= 2 / 444
= 2
Step3:
LCM(2, 942) = 942
GCD(2, 942) = ( 2 x 942 ) / 942
= 2 / 942
= 2
So, Greatest Common Divisor of 686, 386, 444, 942 is 2
