GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(168, 642) = 17976
GCD(168, 642) = ( 168 x 642 ) / 17976
= 168 / 642
= 168
Step2:
LCM(6, 984) = 984
GCD(6, 984) = ( 6 x 984 ) / 984
= 6 / 984
= 6
Step3:
LCM(6, 866) = 2598
GCD(6, 866) = ( 6 x 866 ) / 2598
= 6 / 866
= 6
So, Greatest Common Divisor of 168, 642, 984, 866 is 2
