Lets's calculate LCM of 645,896
Given numbers has no common factors except 1. So, there LCM is their product i.e 577920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 8/577920
Therefore, the GCF of Fractions 6640/645,1256/896 is 8/577920
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 645,896 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(645,896) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(645,896) x common factors =1 x 1 = 1
LCM(645,896) = ( 645 × 896 ) / 1
LCM(645,896) = 577920 / 1
LCM(645,896) = 577920
