So the greatest common factor 612,642 is 6.
Lets's calculate LCM of 380,113
Given numbers has no common factors except 1. So, there LCM is their product i.e 42940
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/42940
Therefore, the GCF of Fractions 612/380,642/113 is 6/42940
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 380,113 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(380,113) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(380,113) x common factors =1 x 1 = 1
LCM(380,113) = ( 380 × 113 ) / 1
LCM(380,113) = 42940 / 1
LCM(380,113) = 42940
