So the greatest common factor 306,638 is 2.
Lets's calculate LCM of 669,638
Given numbers has no common factors except 1. So, there LCM is their product i.e 426822
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/426822
Therefore, the GCF of Fractions 306/669,638/638 is 2/426822
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 669,638 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(669,638) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(669,638) x common factors =1 x 1 = 1
LCM(669,638) = ( 669 × 638 ) / 1
LCM(669,638) = 426822 / 1
LCM(669,638) = 426822
