Lets's calculate LCM of 508,673
Given numbers has no common factors except 1. So, there LCM is their product i.e 341884
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/341884
Therefore, the GCF of Fractions 391/508,440/673 is 1/341884
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 508,673 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(508,673) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(508,673) x common factors =1 x 1 = 1
LCM(508,673) = ( 508 × 673 ) / 1
LCM(508,673) = 341884 / 1
LCM(508,673) = 341884
