We found the factors 840,992,135 . The biggest common factor number is the GCF number.
So the greatest common factor 840,992,135 is 1.
Lets's calculate LCM of 471,309,649
3 | 471, 309, 649 |
157, 103, 649 |
∴ So the LCM of the given numbers is 3 x 157 x 103 x 649 = 31484937
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/31484937
Therefore, the GCF of Fractions 840/471,992/309,135/649 is 1/31484937
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 471,309,649 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(471,309,649) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(471,309,649) x common factors =1 x 3 = 3
LCM(471,309,649) = ( 471 × 309 × 649 ) / 3
LCM(471,309,649) = 94454811 / 3
LCM(471,309,649) = 31484937
