Greatest Common Factor
We found the factors 247,1485 . The biggest common factor number is the GCF number.
So the greatest common factor 247,1485 is 1.
Lets's calculate LCM of 120,678
2 | 120, 678 |
3 | 60, 339 |
20, 113 |
∴ So the LCM of the given numbers is 2 x 3 x 20 x 113 = 13560
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/13560
Therefore, the GCF of Fractions 247/120,1485/678 is 1/13560
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 120,678 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(120,678) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(120,678) x common factors =6 x 1 = 6
LCM(120,678) = ( 120 × 678 ) / 6
LCM(120,678) = 81360 / 6
LCM(120,678) = 13560
