1,5,13,61,65,305,793,3965
Greatest Common Factor
We found the factors 847,3965 . The biggest common factor number is the GCF number.
So the greatest common factor 847,3965 is 1.
Lets's calculate LCM of 197,1291
Given numbers has no common factors except 1. So, there LCM is their product i.e 254327
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/254327
Therefore, the GCF of Fractions 847/197,3965/1291 is 1/254327
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 197,1291 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(197,1291) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(197,1291) x common factors =1 x 1 = 1
LCM(197,1291) = ( 197 × 1291 ) / 1
LCM(197,1291) = 254327 / 1
LCM(197,1291) = 254327
