Lets's calculate LCM of 85,678
Given numbers has no common factors except 1. So, there LCM is their product i.e 57630
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/57630
Therefore, the GCF of Fractions 486/85,868/678 is 2/57630
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 85,678 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,678) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(85,678) x common factors =1 x 1 = 1
LCM(85,678) = ( 85 × 678 ) / 1
LCM(85,678) = 57630 / 1
LCM(85,678) = 57630
