So the greatest common factor 450,646 is 2.
Lets's calculate LCM of 245,853
Given numbers has no common factors except 1. So, there LCM is their product i.e 208985
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/208985
Therefore, the GCF of Fractions 450/245,646/853 is 2/208985
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 245,853 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(245,853) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(245,853) x common factors =1 x 1 = 1
LCM(245,853) = ( 245 × 853 ) / 1
LCM(245,853) = 208985 / 1
LCM(245,853) = 208985
