So the greatest common factor 38,18,354 is 2.
Lets's calculate LCM of 203,386,734
2 | 203, 386, 734 |
203, 193, 367 |
∴ So the LCM of the given numbers is 2 x 203 x 193 x 367 = 28757386
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/28757386
Therefore, the GCF of Fractions 38/203,18/386,354/734 is 2/28757386
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 203,386,734 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(203,386,734) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(203,386,734) x common factors =1 x 2 = 2
LCM(203,386,734) = ( 203 × 386 × 734 ) / 2
LCM(203,386,734) = 57514772 / 2
LCM(203,386,734) = 28757386
