Lets's calculate LCM of 511,581
7 | 511, 581 |
73, 83 |
∴ So the LCM of the given numbers is 7 x 73 x 83 = 42413
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/42413
Therefore, the GCF of Fractions 286/511,644/581 is 2/42413
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 511,581 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(511,581) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(511,581) x common factors =7 x 1 = 7
LCM(511,581) = ( 511 × 581 ) / 7
LCM(511,581) = 296891 / 7
LCM(511,581) = 42413
