We found the factors 1239,4512 . The biggest common factor number is the GCF number.
So the greatest common factor 1239,4512 is 3.
Lets's calculate LCM of 664,274
2 | 664, 274 |
332, 137 |
∴ So the LCM of the given numbers is 2 x 332 x 137 = 90968
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/90968
Therefore, the GCF of Fractions 1239/664,4512/274 is 3/90968
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 664,274 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(664,274) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(664,274) x common factors =2 x 1 = 2
LCM(664,274) = ( 664 × 274 ) / 2
LCM(664,274) = 181936 / 2
LCM(664,274) = 90968
