Lets's calculate LCM of 285,6640
5 | 285, 6640 |
57, 1328 |
∴ So the LCM of the given numbers is 5 x 57 x 1328 = 378480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 166/378480
Therefore, the GCF of Fractions 7470/285,7138/6640 is 166/378480
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 285,6640 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(285,6640) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(285,6640) x common factors =5 x 1 = 5
LCM(285,6640) = ( 285 × 6640 ) / 5
LCM(285,6640) = 1892400 / 5
LCM(285,6640) = 378480
