Greatest Common Factor
We found the factors 137,257 . The biggest common factor number is the GCF number.
So the greatest common factor 137,257 is 1.
Lets's calculate LCM of 981,408
3 | 981, 408 |
327, 136 |
∴ So the LCM of the given numbers is 3 x 327 x 136 = 133416
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/133416
Therefore, the GCF of Fractions 137/981,257/408 is 1/133416
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 981,408 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(981,408) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(981,408) x common factors =3 x 1 = 3
LCM(981,408) = ( 981 × 408 ) / 3
LCM(981,408) = 400248 / 3
LCM(981,408) = 133416
