So the greatest common factor 704,670 is 2.
Lets's calculate LCM of 386,861
Given numbers has no common factors except 1. So, there LCM is their product i.e 332346
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/332346
Therefore, the GCF of Fractions 704/386,670/861 is 2/332346
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 386,861 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(386,861) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(386,861) x common factors =1 x 1 = 1
LCM(386,861) = ( 386 × 861 ) / 1
LCM(386,861) = 332346 / 1
LCM(386,861) = 332346
