We found the factors 391,619 . The biggest common factor number is the GCF number.
So the greatest common factor 391,619 is 1.
Lets's calculate LCM of 212,939
Given numbers has no common factors except 1. So, there LCM is their product i.e 199068
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/199068
Therefore, the GCF of Fractions 391/212,619/939 is 1/199068
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 212,939 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(212,939) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(212,939) x common factors =1 x 1 = 1
LCM(212,939) = ( 212 × 939 ) / 1
LCM(212,939) = 199068 / 1
LCM(212,939) = 199068
