So the greatest common factor 777,870 is 3.
Lets's calculate LCM of 789,503
Given numbers has no common factors except 1. So, there LCM is their product i.e 396867
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/396867
Therefore, the GCF of Fractions 777/789,870/503 is 3/396867
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 789,503 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(789,503) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(789,503) x common factors =1 x 1 = 1
LCM(789,503) = ( 789 × 503 ) / 1
LCM(789,503) = 396867 / 1
LCM(789,503) = 396867
