Lets's calculate LCM of 217,3384
Given numbers has no common factors except 1. So, there LCM is their product i.e 734328
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/734328
Therefore, the GCF of Fractions 490/217,4918/3384 is 2/734328
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 217,3384 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(217,3384) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(217,3384) x common factors =1 x 1 = 1
LCM(217,3384) = ( 217 × 3384 ) / 1
LCM(217,3384) = 734328 / 1
LCM(217,3384) = 734328
