Greatest Common Factor
We found the factors 938,238 . The biggest common factor number is the GCF number.
So the greatest common factor 938,238 is 14.
Lets's calculate LCM of 472,930
2 | 472, 930 |
236, 465 |
∴ So the LCM of the given numbers is 2 x 236 x 465 = 219480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 14/219480
Therefore, the GCF of Fractions 938/472,238/930 is 14/219480
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 472,930 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(472,930) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(472,930) x common factors =2 x 1 = 2
LCM(472,930) = ( 472 × 930 ) / 2
LCM(472,930) = 438960 / 2
LCM(472,930) = 219480
