Lets's calculate LCM of 194,464
2 | 194, 464 |
97, 232 |
∴ So the LCM of the given numbers is 2 x 97 x 232 = 45008
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/45008
Therefore, the GCF of Fractions 398/194,246/464 is 2/45008
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 194,464 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(194,464) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(194,464) x common factors =2 x 1 = 2
LCM(194,464) = ( 194 × 464 ) / 2
LCM(194,464) = 90016 / 2
LCM(194,464) = 45008
