Lets's calculate LCM of 906,859
Given numbers has no common factors except 1. So, there LCM is their product i.e 778254
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/778254
Therefore, the GCF of Fractions 680/906,6786/859 is 2/778254
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 906,859 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(906,859) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(906,859) x common factors =1 x 1 = 1
LCM(906,859) = ( 906 × 859 ) / 1
LCM(906,859) = 778254 / 1
LCM(906,859) = 778254
Here are some samples of GCF of Fractions calculations.
