So the greatest common factor 835,702 is 1.
Lets's calculate LCM of 470,794
2 | 470, 794 |
235, 397 |
∴ So the LCM of the given numbers is 2 x 235 x 397 = 186590
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/186590
Therefore, the GCF of Fractions 835/470,702/794 is 1/186590
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 470,794 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(470,794) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(470,794) x common factors =2 x 1 = 2
LCM(470,794) = ( 470 × 794 ) / 2
LCM(470,794) = 373180 / 2
LCM(470,794) = 186590
