Lets's calculate LCM of 820,684
2 | 820, 684 |
2 | 410, 342 |
205, 171 |
∴ So the LCM of the given numbers is 2 x 2 x 205 x 171 = 140220
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/140220
Therefore, the GCF of Fractions 459/820,771/684 is 3/140220
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 820,684 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(820,684) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(820,684) x common factors =4 x 1 = 4
LCM(820,684) = ( 820 × 684 ) / 4
LCM(820,684) = 560880 / 4
LCM(820,684) = 140220
