Greatest Common Factor
We found the factors 1680,4989 . The biggest common factor number is the GCF number.
So the greatest common factor 1680,4989 is 3.
Lets's calculate LCM of 203,238
7 | 203, 238 |
29, 34 |
∴ So the LCM of the given numbers is 7 x 29 x 34 = 6902
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/6902
Therefore, the GCF of Fractions 1680/203,4989/238 is 3/6902
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 203,238 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(203,238) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(203,238) x common factors =7 x 1 = 7
LCM(203,238) = ( 203 × 238 ) / 7
LCM(203,238) = 48314 / 7
LCM(203,238) = 6902
