So the greatest common factor 447,798 is 3.
Lets's calculate LCM of 271,746
Given numbers has no common factors except 1. So, there LCM is their product i.e 202166
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/202166
Therefore, the GCF of Fractions 447/271,798/746 is 3/202166
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 271,746 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(271,746) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(271,746) x common factors =1 x 1 = 1
LCM(271,746) = ( 271 × 746 ) / 1
LCM(271,746) = 202166 / 1
LCM(271,746) = 202166
