Lets's calculate LCM of 768,581
Given numbers has no common factors except 1. So, there LCM is their product i.e 446208
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/446208
Therefore, the GCF of Fractions 778/768,4638/581 is 2/446208
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 768,581 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(768,581) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(768,581) x common factors =1 x 1 = 1
LCM(768,581) = ( 768 × 581 ) / 1
LCM(768,581) = 446208 / 1
LCM(768,581) = 446208
