So the greatest common factor 425,405 is 5.
Lets's calculate LCM of 739,868
Given numbers has no common factors except 1. So, there LCM is their product i.e 641452
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/641452
Therefore, the GCF of Fractions 425/739,405/868 is 5/641452
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 739,868 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(739,868) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(739,868) x common factors =1 x 1 = 1
LCM(739,868) = ( 739 × 868 ) / 1
LCM(739,868) = 641452 / 1
LCM(739,868) = 641452
