Lets's calculate LCM of 981,640
Given numbers has no common factors except 1. So, there LCM is their product i.e 627840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/627840
Therefore, the GCF of Fractions 393/981,8586/640 is 3/627840
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 981,640 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(981,640) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(981,640) x common factors =1 x 1 = 1
LCM(981,640) = ( 981 × 640 ) / 1
LCM(981,640) = 627840 / 1
LCM(981,640) = 627840
