So the greatest common factor 311,456 is 1.
Lets's calculate LCM of 189,578
Given numbers has no common factors except 1. So, there LCM is their product i.e 109242
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/109242
Therefore, the GCF of Fractions 311/189,456/578 is 1/109242
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 189,578 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(189,578) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(189,578) x common factors =1 x 1 = 1
LCM(189,578) = ( 189 × 578 ) / 1
LCM(189,578) = 109242 / 1
LCM(189,578) = 109242
