Lets's calculate LCM of 21,403
Given numbers has no common factors except 1. So, there LCM is their product i.e 8463
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/8463
Therefore, the GCF of Fractions 308/21,141/403 is 1/8463
Least Common Multiple of 21,403 with GCF Formula
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 21,403 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,403) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(21,403) x common factors =1 x 1 = 1
LCM(21,403) = ( 21 × 403 ) / 1
LCM(21,403) = 8463 / 1
LCM(21,403) = 8463
