So the greatest common factor 870,642 is 6.
Lets's calculate LCM of 199,648
Given numbers has no common factors except 1. So, there LCM is their product i.e 128952
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/128952
Therefore, the GCF of Fractions 870/199,642/648 is 6/128952
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 199,648 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(199,648) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(199,648) x common factors =1 x 1 = 1
LCM(199,648) = ( 199 × 648 ) / 1
LCM(199,648) = 128952 / 1
LCM(199,648) = 128952
