Lets's calculate LCM of 404,676
2 | 404, 676 |
2 | 202, 338 |
101, 169 |
∴ So the LCM of the given numbers is 2 x 2 x 101 x 169 = 68276
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/68276
Therefore, the GCF of Fractions 578/404,970/676 is 2/68276
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 404,676 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(404,676) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(404,676) x common factors =4 x 1 = 4
LCM(404,676) = ( 404 × 676 ) / 4
LCM(404,676) = 273104 / 4
LCM(404,676) = 68276
