Lets's calculate LCM of 478,757
Given numbers has no common factors except 1. So, there LCM is their product i.e 361846
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/361846
Therefore, the GCF of Fractions 867/478,819/757 is 3/361846
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 478,757 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(478,757) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(478,757) x common factors =1 x 1 = 1
LCM(478,757) = ( 478 × 757 ) / 1
LCM(478,757) = 361846 / 1
LCM(478,757) = 361846
