The factors of 831 are 1, 3, 277, 831
The HCF of 351,831 is 3.
Lets's calculate GCF of 351,831
3 | 351, 831 |
117, 277 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 351
:1,3,9,13,27,39,117,351
Now, list down the factors of 831
:1,3,277,831
Greatest Common Factor
We found the factors 351,831 . The biggest common factor number is the GCF number.
So the greatest common factor 351,831 is 3.
Lets's calculate LCM of 651,698
Given numbers has no common factors except 1. So, there LCM is their product i.e 454398
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/454398
Therefore, the GCF of Fractions 351/651,831/698 is 3/454398
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 651,698 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(651,698) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(651,698) x common factors =1 x 1 = 1
LCM(651,698) = ( 651 × 698 ) / 1
LCM(651,698) = 454398 / 1
LCM(651,698) = 454398
