So the greatest common factor 868,140 is 28.
Lets's calculate LCM of 205,974
Given numbers has no common factors except 1. So, there LCM is their product i.e 199670
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 28/199670
Therefore, the GCF of Fractions 868/205,140/974 is 28/199670
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 205,974 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(205,974) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(205,974) x common factors =1 x 1 = 1
LCM(205,974) = ( 205 × 974 ) / 1
LCM(205,974) = 199670 / 1
LCM(205,974) = 199670
