The factors of 831 are 1, 3, 277, 831
The HCF of 706,831 is 1.
Lets's calculate GCF of 706,831
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 706
:1,2,353,706
Now, list down the factors of 831
:1,3,277,831
Greatest Common Factor
We found the factors 706,831 . The biggest common factor number is the GCF number.
So the greatest common factor 706,831 is 1.
Lets's calculate LCM of 471,490
Given numbers has no common factors except 1. So, there LCM is their product i.e 230790
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/230790
Therefore, the GCF of Fractions 706/471,831/490 is 1/230790
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 471,490 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(471,490) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(471,490) x common factors =1 x 1 = 1
LCM(471,490) = ( 471 × 490 ) / 1
LCM(471,490) = 230790 / 1
LCM(471,490) = 230790
