GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(891, 388) = 345708
GCD(891, 388) = ( 891 x 388 ) / 345708
= 891 / 388
= 891
Step2:
LCM(1, 385) = 385
GCD(1, 385) = ( 1 x 385 ) / 385
= 1 / 385
= 1
Step3:
LCM(1, 866) = 866
GCD(1, 866) = ( 1 x 866 ) / 866
= 1 / 866
= 1
So, Greatest Common Divisor of 891, 388, 385, 866 is 1
