So the greatest common factor 838,810 is 2.
Lets's calculate LCM of 287,772
Given numbers has no common factors except 1. So, there LCM is their product i.e 221564
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/221564
Therefore, the GCF of Fractions 838/287,810/772 is 2/221564
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 287,772 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(287,772) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(287,772) x common factors =1 x 1 = 1
LCM(287,772) = ( 287 × 772 ) / 1
LCM(287,772) = 221564 / 1
LCM(287,772) = 221564
