Greatest Common Factor
We found the factors 8640,1386 . The biggest common factor number is the GCF number.
So the greatest common factor 8640,1386 is 18.
Lets's calculate LCM of 315,190
5 | 315, 190 |
63, 38 |
∴ So the LCM of the given numbers is 5 x 63 x 38 = 11970
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 18/11970
Therefore, the GCF of Fractions 8640/315,1386/190 is 18/11970
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 315,190 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(315,190) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(315,190) x common factors =5 x 1 = 5
LCM(315,190) = ( 315 × 190 ) / 5
LCM(315,190) = 59850 / 5
LCM(315,190) = 11970
