Lets's calculate LCM of 543,678
3 | 543, 678 |
181, 226 |
∴ So the LCM of the given numbers is 3 x 181 x 226 = 122718
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/122718
Therefore, the GCF of Fractions 424/543,942/678 is 2/122718
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 543,678 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(543,678) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(543,678) x common factors =3 x 1 = 3
LCM(543,678) = ( 543 × 678 ) / 3
LCM(543,678) = 368154 / 3
LCM(543,678) = 122718
