So the greatest common factor 297,378 is 27.
Lets's calculate LCM of 663,307
Given numbers has no common factors except 1. So, there LCM is their product i.e 203541
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 27/203541
Therefore, the GCF of Fractions 297/663,378/307 is 27/203541
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 663,307 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(663,307) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(663,307) x common factors =1 x 1 = 1
LCM(663,307) = ( 663 × 307 ) / 1
LCM(663,307) = 203541 / 1
LCM(663,307) = 203541
