:1,2,61,122
Now, list down the factors of 691
:1,691
Greatest Common Factor
We found the factors 122,691 . The biggest common factor number is the GCF number.
So the greatest common factor 122,691 is 1.
Lets's calculate LCM of 391,242
Given numbers has no common factors except 1. So, there LCM is their product i.e 94622
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/94622
Therefore, the GCF of Fractions 122/391,691/242 is 1/94622
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 391,242 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(391,242) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(391,242) x common factors =1 x 1 = 1
LCM(391,242) = ( 391 × 242 ) / 1
LCM(391,242) = 94622 / 1
LCM(391,242) = 94622
