Greatest Common Factor
We found the factors 945,845 . The biggest common factor number is the GCF number.
So the greatest common factor 945,845 is 5.
Lets's calculate LCM of 7889,1089
Given numbers has no common factors except 1. So, there LCM is their product i.e 8591121
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/8591121
Therefore, the GCF of Fractions 945/7889,845/1089 is 5/8591121
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 7889,1089 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(7889,1089) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(7889,1089) x common factors =1 x 1 = 1
LCM(7889,1089) = ( 7889 × 1089 ) / 1
LCM(7889,1089) = 8591121 / 1
LCM(7889,1089) = 8591121
