Lets's calculate LCM of 972,809,289
Given numbers has no common factors except 1. So, there LCM is their product i.e 227254572
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/227254572
Therefore, the GCF of Fractions 947/972,213/809,331/289 is 1/227254572
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 972,809,289 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(972,809,289) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(972,809,289) x common factors =1 x 1 = 1
LCM(972,809,289) = ( 972 × 809 × 289 ) / 1
LCM(972,809,289) = 227254572 / 1
LCM(972,809,289) = 227254572
