Lets's calculate LCM of 249,4210
Given numbers has no common factors except 1. So, there LCM is their product i.e 1048290
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/1048290
Therefore, the GCF of Fractions 7780/249,4086/4210 is 2/1048290
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 249,4210 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(249,4210) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(249,4210) x common factors =1 x 1 = 1
LCM(249,4210) = ( 249 × 4210 ) / 1
LCM(249,4210) = 1048290 / 1
LCM(249,4210) = 1048290
