Lets's calculate LCM of 994,243
Given numbers has no common factors except 1. So, there LCM is their product i.e 241542
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/241542
Therefore, the GCF of Fractions 386/994,946/243 is 2/241542
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 994,243 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(994,243) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(994,243) x common factors =1 x 1 = 1
LCM(994,243) = ( 994 × 243 ) / 1
LCM(994,243) = 241542 / 1
LCM(994,243) = 241542
