Lets's calculate LCM of 491,478,682
2 | 491, 478, 682 |
491, 239, 341 |
∴ So the LCM of the given numbers is 2 x 491 x 239 x 341 = 80032018
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/80032018
Therefore, the GCF of Fractions 54/491,28/478,949/682 is 1/80032018
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 491,478,682 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(491,478,682) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(491,478,682) x common factors =1 x 2 = 2
LCM(491,478,682) = ( 491 × 478 × 682 ) / 2
LCM(491,478,682) = 160064036 / 2
LCM(491,478,682) = 80032018
