Lets's calculate LCM of 517,863
Given numbers has no common factors except 1. So, there LCM is their product i.e 446171
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/446171
Therefore, the GCF of Fractions 847/517,7728/863 is 7/446171
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 517,863 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(517,863) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(517,863) x common factors =1 x 1 = 1
LCM(517,863) = ( 517 × 863 ) / 1
LCM(517,863) = 446171 / 1
LCM(517,863) = 446171
