Greatest Common Factor
We found the factors 230,478 . The biggest common factor number is the GCF number.
So the greatest common factor 230,478 is 2.
Lets's calculate LCM of 38,4430
2 | 38, 4430 |
19, 2215 |
∴ So the LCM of the given numbers is 2 x 19 x 2215 = 84170
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/84170
Therefore, the GCF of Fractions 230/38,478/4430 is 2/84170
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 38,4430 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(38,4430) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(38,4430) x common factors =2 x 1 = 2
LCM(38,4430) = ( 38 × 4430 ) / 2
LCM(38,4430) = 168340 / 2
LCM(38,4430) = 84170
