Greatest Common Factor
We found the factors 394,711 . The biggest common factor number is the GCF number.
So the greatest common factor 394,711 is 1.
Lets's calculate LCM of 442,638
2 | 442, 638 |
221, 319 |
∴ So the LCM of the given numbers is 2 x 221 x 319 = 140998
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/140998
Therefore, the GCF of Fractions 394/442,711/638 is 1/140998
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 442,638 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(442,638) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(442,638) x common factors =2 x 1 = 2
LCM(442,638) = ( 442 × 638 ) / 2
LCM(442,638) = 281996 / 2
LCM(442,638) = 140998
