Lets's calculate LCM of 385,2301
Given numbers has no common factors except 1. So, there LCM is their product i.e 885885
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/885885
Therefore, the GCF of Fractions 66/385,1258/2301 is 2/885885
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 385,2301 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(385,2301) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(385,2301) x common factors =1 x 1 = 1
LCM(385,2301) = ( 385 × 2301 ) / 1
LCM(385,2301) = 885885 / 1
LCM(385,2301) = 885885
