So the greatest common factor 756,3070 is 2.
Lets's calculate LCM of 55,298
Given numbers has no common factors except 1. So, there LCM is their product i.e 16390
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/16390
Therefore, the GCF of Fractions 756/55,3070/298 is 2/16390
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 55,298 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(55,298) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(55,298) x common factors =1 x 1 = 1
LCM(55,298) = ( 55 × 298 ) / 1
LCM(55,298) = 16390 / 1
LCM(55,298) = 16390
