Lets's calculate LCM of 821,2115
Given numbers has no common factors except 1. So, there LCM is their product i.e 1736415
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/1736415
Therefore, the GCF of Fractions 2975/821,3934/2115 is 7/1736415
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 821,2115 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(821,2115) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(821,2115) x common factors =1 x 1 = 1
LCM(821,2115) = ( 821 × 2115 ) / 1
LCM(821,2115) = 1736415 / 1
LCM(821,2115) = 1736415
