Greatest Common Factor
We found the factors 7700,3948 . The biggest common factor number is the GCF number.
So the greatest common factor 7700,3948 is 28.
Lets's calculate LCM of 85,419
Given numbers has no common factors except 1. So, there LCM is their product i.e 35615
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 28/35615
Therefore, the GCF of Fractions 7700/85,3948/419 is 28/35615
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 85,419 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,419) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(85,419) x common factors =1 x 1 = 1
LCM(85,419) = ( 85 × 419 ) / 1
LCM(85,419) = 35615 / 1
LCM(85,419) = 35615
