Given numbers are 876, 970, 991, 891
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(876, 970) = 424860
GCD(876, 970) = ( 876 x 970 ) / 424860
= 876 / 970
= 876
Step2:
LCM(2, 991) = 1982
GCD(2, 991) = ( 2 x 991 ) / 1982
= 2 / 991
= 2
Step3:
LCM(1, 891) = 891
GCD(1, 891) = ( 1 x 891 ) / 891
= 1 / 891
= 1
So, Greatest Common Divisor of 876, 970, 991, 891 is 1
