Lets's calculate LCM of 809,881
Given numbers has no common factors except 1. So, there LCM is their product i.e 712729
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/712729
Therefore, the GCF of Fractions 2139/809,4845/881 is 3/712729
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 809,881 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(809,881) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(809,881) x common factors =1 x 1 = 1
LCM(809,881) = ( 809 × 881 ) / 1
LCM(809,881) = 712729 / 1
LCM(809,881) = 712729
