So the greatest common factor 218,640 is 2.
Lets's calculate LCM of 371,101
Given numbers has no common factors except 1. So, there LCM is their product i.e 37471
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/37471
Therefore, the GCF of Fractions 218/371,640/101 is 2/37471
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 371,101 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(371,101) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(371,101) x common factors =1 x 1 = 1
LCM(371,101) = ( 371 × 101 ) / 1
LCM(371,101) = 37471 / 1
LCM(371,101) = 37471
