So the greatest common factor 975,870 is 15.
Lets's calculate LCM of 705,459
3 | 705, 459 |
235, 153 |
∴ So the LCM of the given numbers is 3 x 235 x 153 = 107865
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/107865
Therefore, the GCF of Fractions 975/705,870/459 is 15/107865
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 705,459 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(705,459) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(705,459) x common factors =3 x 1 = 3
LCM(705,459) = ( 705 × 459 ) / 3
LCM(705,459) = 323595 / 3
LCM(705,459) = 107865
