Greatest Common Factor
We found the factors 73,86,921 . The biggest common factor number is the GCF number.
So the greatest common factor 73,86,921 is 1.
Lets's calculate LCM of 309,804,517
3 | 309, 804, 517 |
103, 268, 517 |
∴ So the LCM of the given numbers is 3 x 103 x 268 x 517 = 42813804
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/42813804
Therefore, the GCF of Fractions 73/309,86/804,921/517 is 1/42813804
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 309,804,517 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(309,804,517) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(309,804,517) x common factors =1 x 3 = 3
LCM(309,804,517) = ( 309 × 804 × 517 ) / 3
LCM(309,804,517) = 128441412 / 3
LCM(309,804,517) = 42813804
