1,2,4,7,14,28,167,334,668,1169,2338,4676
Greatest Common Factor
We found the factors 489,4676 . The biggest common factor number is the GCF number.
So the greatest common factor 489,4676 is 1.
Lets's calculate LCM of 691,395
Given numbers has no common factors except 1. So, there LCM is their product i.e 272945
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/272945
Therefore, the GCF of Fractions 489/691,4676/395 is 1/272945
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 691,395 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(691,395) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(691,395) x common factors =1 x 1 = 1
LCM(691,395) = ( 691 × 395 ) / 1
LCM(691,395) = 272945 / 1
LCM(691,395) = 272945
