So the greatest common factor 426,768 is 6.
Lets's calculate LCM of 905,789
Given numbers has no common factors except 1. So, there LCM is their product i.e 714045
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/714045
Therefore, the GCF of Fractions 426/905,768/789 is 6/714045
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 905,789 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(905,789) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(905,789) x common factors =1 x 1 = 1
LCM(905,789) = ( 905 × 789 ) / 1
LCM(905,789) = 714045 / 1
LCM(905,789) = 714045
