Greatest Common Factor
We found the factors 454,393 . The biggest common factor number is the GCF number.
So the greatest common factor 454,393 is 1.
Lets's calculate LCM of 906,808
2 | 906, 808 |
453, 404 |
∴ So the LCM of the given numbers is 2 x 453 x 404 = 366024
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/366024
Therefore, the GCF of Fractions 454/906,393/808 is 1/366024
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 906,808 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(906,808) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(906,808) x common factors =2 x 1 = 2
LCM(906,808) = ( 906 × 808 ) / 2
LCM(906,808) = 732048 / 2
LCM(906,808) = 366024
