We found the factors 495,720 . The biggest common factor number is the GCF number.
So the greatest common factor 495,720 is 45.
Lets's calculate LCM of 507,547
Given numbers has no common factors except 1. So, there LCM is their product i.e 277329
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 45/277329
Therefore, the GCF of Fractions 495/507,720/547 is 45/277329
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 507,547 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(507,547) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(507,547) x common factors =1 x 1 = 1
LCM(507,547) = ( 507 × 547 ) / 1
LCM(507,547) = 277329 / 1
LCM(507,547) = 277329
