Given numbers are 891, 210, 381, 386
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(891, 210) = 62370
GCD(891, 210) = ( 891 x 210 ) / 62370
= 891 / 210
= 891
Step2:
LCM(3, 381) = 381
GCD(3, 381) = ( 3 x 381 ) / 381
= 3 / 381
= 3
Step3:
LCM(3, 386) = 1158
GCD(3, 386) = ( 3 x 386 ) / 1158
= 3 / 386
= 3
So, Greatest Common Divisor of 891, 210, 381, 386 is 1
