So the greatest common factor 1278,4305 is 3.
Lets's calculate LCM of 68,807
Given numbers has no common factors except 1. So, there LCM is their product i.e 54876
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/54876
Therefore, the GCF of Fractions 1278/68,4305/807 is 3/54876
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 68,807 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(68,807) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(68,807) x common factors =1 x 1 = 1
LCM(68,807) = ( 68 × 807 ) / 1
LCM(68,807) = 54876 / 1
LCM(68,807) = 54876
