So the greatest common factor 663,291 is 3.
Lets's calculate LCM of 30,1217
Given numbers has no common factors except 1. So, there LCM is their product i.e 36510
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/36510
Therefore, the GCF of Fractions 663/30,291/1217 is 3/36510
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 30,1217 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,1217) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(30,1217) x common factors =1 x 1 = 1
LCM(30,1217) = ( 30 × 1217 ) / 1
LCM(30,1217) = 36510 / 1
LCM(30,1217) = 36510
