Greatest Common Factor
We found the factors 792,643 . The biggest common factor number is the GCF number.
So the greatest common factor 792,643 is 1.
Lets's calculate LCM of 858,303
3 | 858, 303 |
286, 101 |
∴ So the LCM of the given numbers is 3 x 286 x 101 = 86658
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/86658
Therefore, the GCF of Fractions 792/858,643/303 is 1/86658
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 858,303 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(858,303) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(858,303) x common factors =3 x 1 = 3
LCM(858,303) = ( 858 × 303 ) / 3
LCM(858,303) = 259974 / 3
LCM(858,303) = 86658
