Greatest Common Factor
We found the factors 798,106 . The biggest common factor number is the GCF number.
So the greatest common factor 798,106 is 2.
Lets's calculate LCM of 428,834
2 | 428, 834 |
214, 417 |
∴ So the LCM of the given numbers is 2 x 214 x 417 = 178476
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/178476
Therefore, the GCF of Fractions 798/428,106/834 is 2/178476
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 428,834 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(428,834) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(428,834) x common factors =2 x 1 = 2
LCM(428,834) = ( 428 × 834 ) / 2
LCM(428,834) = 356952 / 2
LCM(428,834) = 178476
