Lets's calculate GCF of 7831,1071
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 7831
:1,41,191,7831
Now, list down the factors of 1071
:1,3,7,9,17,21,51,63,119,153,357,1071
Greatest Common Factor
We found the factors 7831,1071 . The biggest common factor number is the GCF number.
So the greatest common factor 7831,1071 is 1.
Lets's calculate LCM of 105,979
Given numbers has no common factors except 1. So, there LCM is their product i.e 102795
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/102795
Therefore, the GCF of Fractions 7831/105,1071/979 is 1/102795
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 105,979 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(105,979) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(105,979) x common factors =1 x 1 = 1
LCM(105,979) = ( 105 × 979 ) / 1
LCM(105,979) = 102795 / 1
LCM(105,979) = 102795
