Lets's calculate LCM of 477,8442
3 | 477, 8442 |
3 | 159, 2814 |
53, 938 |
∴ So the LCM of the given numbers is 3 x 3 x 53 x 938 = 447426
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/447426
Therefore, the GCF of Fractions 6421/477,4551/8442 is 1/447426
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 477,8442 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(477,8442) = 9
common factors(in case of two or more numbers have common factors) = 1
GCF(477,8442) x common factors =9 x 1 = 9
LCM(477,8442) = ( 477 × 8442 ) / 9
LCM(477,8442) = 4026834 / 9
LCM(477,8442) = 447426
