So the greatest common factor 3888,2871 is 9.
Lets's calculate LCM of 25,790
5 | 25, 790 |
5, 158 |
∴ So the LCM of the given numbers is 5 x 5 x 158 = 3950
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/3950
Therefore, the GCF of Fractions 3888/25,2871/790 is 9/3950
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 25,790 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(25,790) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(25,790) x common factors =5 x 1 = 5
LCM(25,790) = ( 25 × 790 ) / 5
LCM(25,790) = 19750 / 5
LCM(25,790) = 3950
