Lets's calculate LCM of 461,477
Given numbers has no common factors except 1. So, there LCM is their product i.e 219897
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/219897
Therefore, the GCF of Fractions 812/461,2388/477 is 4/219897
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 461,477 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(461,477) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(461,477) x common factors =1 x 1 = 1
LCM(461,477) = ( 461 × 477 ) / 1
LCM(461,477) = 219897 / 1
LCM(461,477) = 219897
Here are some samples of GCF of Fractions calculations.
