So the greatest common factor 845,858 is 13.
Lets's calculate LCM of 70,585
5 | 70, 585 |
14, 117 |
∴ So the LCM of the given numbers is 5 x 14 x 117 = 8190
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/8190
Therefore, the GCF of Fractions 845/70,858/585 is 13/8190
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 70,585 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,585) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(70,585) x common factors =5 x 1 = 5
LCM(70,585) = ( 70 × 585 ) / 5
LCM(70,585) = 40950 / 5
LCM(70,585) = 8190
