Lets's calculate LCM of 507,842
Given numbers has no common factors except 1. So, there LCM is their product i.e 426894
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/426894
Therefore, the GCF of Fractions 605/507,639/842 is 1/426894
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 507,842 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(507,842) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(507,842) x common factors =1 x 1 = 1
LCM(507,842) = ( 507 × 842 ) / 1
LCM(507,842) = 426894 / 1
LCM(507,842) = 426894
