So the greatest common factor 126,845 is 1.
Lets's calculate LCM of 402,669
3 | 402, 669 |
134, 223 |
∴ So the LCM of the given numbers is 3 x 134 x 223 = 89646
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/89646
Therefore, the GCF of Fractions 126/402,845/669 is 1/89646
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 402,669 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(402,669) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(402,669) x common factors =3 x 1 = 3
LCM(402,669) = ( 402 × 669 ) / 3
LCM(402,669) = 268938 / 3
LCM(402,669) = 89646
