The factors of 131 are 1, 131
The factors of 831 are 1, 3, 277, 831
The HCF of 131,831 is 1.
Lets's calculate GCF of 131,831
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 131
:1,131
Now, list down the factors of 831
:1,3,277,831
Greatest Common Factor
We found the factors 131,831 . The biggest common factor number is the GCF number.
So the greatest common factor 131,831 is 1.
Lets's calculate LCM of 401,781
Given numbers has no common factors except 1. So, there LCM is their product i.e 313181
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/313181
Therefore, the GCF of Fractions 131/401,831/781 is 1/313181
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 401,781 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(401,781) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(401,781) x common factors =1 x 1 = 1
LCM(401,781) = ( 401 × 781 ) / 1
LCM(401,781) = 313181 / 1
LCM(401,781) = 313181
