So the greatest common factor 747,9945 is 9.
Lets's calculate LCM of 689,6689
Given numbers has no common factors except 1. So, there LCM is their product i.e 4608721
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/4608721
Therefore, the GCF of Fractions 747/689,9945/6689 is 9/4608721
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 689,6689 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(689,6689) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(689,6689) x common factors =1 x 1 = 1
LCM(689,6689) = ( 689 × 6689 ) / 1
LCM(689,6689) = 4608721 / 1
LCM(689,6689) = 4608721
