We found the factors 456,6438 . The biggest common factor number is the GCF number.
So the greatest common factor 456,6438 is 6.
Lets's calculate LCM of 714,891
3 | 714, 891 |
238, 297 |
∴ So the LCM of the given numbers is 3 x 238 x 297 = 212058
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/212058
Therefore, the GCF of Fractions 456/714,6438/891 is 6/212058
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 714,891 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(714,891) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(714,891) x common factors =3 x 1 = 3
LCM(714,891) = ( 714 × 891 ) / 3
LCM(714,891) = 636174 / 3
LCM(714,891) = 212058
