Greatest Common Factor
We found the factors 478,490 . The biggest common factor number is the GCF number.
So the greatest common factor 478,490 is 2.
Lets's calculate LCM of 30,9422
2 | 30, 9422 |
15, 4711 |
∴ So the LCM of the given numbers is 2 x 15 x 4711 = 141330
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/141330
Therefore, the GCF of Fractions 478/30,490/9422 is 2/141330
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 30,9422 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,9422) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(30,9422) x common factors =2 x 1 = 2
LCM(30,9422) = ( 30 × 9422 ) / 2
LCM(30,9422) = 282660 / 2
LCM(30,9422) = 141330
