We found the factors 618,5642 . The biggest common factor number is the GCF number.
So the greatest common factor 618,5642 is 2.
Lets's calculate LCM of 991,241
Given numbers has no common factors except 1. So, there LCM is their product i.e 238831
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/238831
Therefore, the GCF of Fractions 618/991,5642/241 is 2/238831
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 991,241 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(991,241) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(991,241) x common factors =1 x 1 = 1
LCM(991,241) = ( 991 × 241 ) / 1
LCM(991,241) = 238831 / 1
LCM(991,241) = 238831
