Given numbers are 891, 140, 538, 943
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(891, 140) = 124740
GCD(891, 140) = ( 891 x 140 ) / 124740
= 891 / 140
= 891
Step2:
LCM(1, 538) = 538
GCD(1, 538) = ( 1 x 538 ) / 538
= 1 / 538
= 1
Step3:
LCM(1, 943) = 943
GCD(1, 943) = ( 1 x 943 ) / 943
= 1 / 943
= 1
So, Greatest Common Divisor of 891, 140, 538, 943 is 1
