So the greatest common factor 288,618 is 6.
Lets's calculate LCM of 805,434
7 | 805, 434 |
115, 62 |
∴ So the LCM of the given numbers is 7 x 115 x 62 = 49910
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/49910
Therefore, the GCF of Fractions 288/805,618/434 is 6/49910
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 805,434 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(805,434) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(805,434) x common factors =7 x 1 = 7
LCM(805,434) = ( 805 × 434 ) / 7
LCM(805,434) = 349370 / 7
LCM(805,434) = 49910
