Lets's calculate LCM of 391,1256
Given numbers has no common factors except 1. So, there LCM is their product i.e 491096
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/491096
Therefore, the GCF of Fractions 220/391,3254/1256 is 2/491096
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 391,1256 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(391,1256) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(391,1256) x common factors =1 x 1 = 1
LCM(391,1256) = ( 391 × 1256 ) / 1
LCM(391,1256) = 491096 / 1
LCM(391,1256) = 491096
