Now, list down the factors of 197
:1,197
Now, list down the factors of 309
:1,3,103,309
Greatest Common Factor
We found the factors 197,309 . The biggest common factor number is the GCF number.
So the greatest common factor 197,309 is 1.
Lets's calculate LCM of 81,4921
Given numbers has no common factors except 1. So, there LCM is their product i.e 398601
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/398601
Therefore, the GCF of Fractions 197/81,309/4921 is 1/398601
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 81,4921 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,4921) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(81,4921) x common factors =1 x 1 = 1
LCM(81,4921) = ( 81 × 4921 ) / 1
LCM(81,4921) = 398601 / 1
LCM(81,4921) = 398601
