Lets's calculate LCM of 23,4973
Given numbers has no common factors except 1. So, there LCM is their product i.e 114379
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/114379
Therefore, the GCF of Fractions 216/23,470/4973 is 2/114379
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 23,4973 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(23,4973) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(23,4973) x common factors =1 x 1 = 1
LCM(23,4973) = ( 23 × 4973 ) / 1
LCM(23,4973) = 114379 / 1
LCM(23,4973) = 114379
