So the greatest common factor 458,788 is 2.
Lets's calculate LCM of 386,263
Given numbers has no common factors except 1. So, there LCM is their product i.e 101518
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/101518
Therefore, the GCF of Fractions 458/386,788/263 is 2/101518
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 386,263 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(386,263) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(386,263) x common factors =1 x 1 = 1
LCM(386,263) = ( 386 × 263 ) / 1
LCM(386,263) = 101518 / 1
LCM(386,263) = 101518
