GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(684, 393) = 89604
GCD(684, 393) = ( 684 x 393 ) / 89604
= 684 / 393
= 684
Step2:
LCM(3, 942) = 942
GCD(3, 942) = ( 3 x 942 ) / 942
= 3 / 942
= 3
Step3:
LCM(3, 687) = 687
GCD(3, 687) = ( 3 x 687 ) / 687
= 3 / 687
= 3
So, Greatest Common Divisor of 684, 393, 942, 687 is 3
