Lets's calculate LCM of 257,4384
Given numbers has no common factors except 1. So, there LCM is their product i.e 1126688
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 17/1126688
Therefore, the GCF of Fractions 1649/257,1938/4384 is 17/1126688
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 257,4384 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(257,4384) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(257,4384) x common factors =1 x 1 = 1
LCM(257,4384) = ( 257 × 4384 ) / 1
LCM(257,4384) = 1126688 / 1
LCM(257,4384) = 1126688
