Greatest Common Factor
We found the factors 210,745 . The biggest common factor number is the GCF number.
So the greatest common factor 210,745 is 5.
Lets's calculate LCM of 823,419
Given numbers has no common factors except 1. So, there LCM is their product i.e 344837
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/344837
Therefore, the GCF of Fractions 210/823,745/419 is 5/344837
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 823,419 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(823,419) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(823,419) x common factors =1 x 1 = 1
LCM(823,419) = ( 823 × 419 ) / 1
LCM(823,419) = 344837 / 1
LCM(823,419) = 344837
