So the greatest common factor 308,346,794 is 2.
Lets's calculate LCM of 81,80,709
Given numbers has no common factors except 1. So, there LCM is their product i.e 4594320
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/4594320
Therefore, the GCF of Fractions 308/81,346/80,794/709 is 2/4594320
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 81,80,709 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,80,709) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(81,80,709) x common factors =1 x 1 = 1
LCM(81,80,709) = ( 81 × 80 × 709 ) / 1
LCM(81,80,709) = 4594320 / 1
LCM(81,80,709) = 4594320
Here are some samples of GCF of Fractions calculations.
