Lets's calculate LCM of 398,1456
2 | 398, 1456 |
199, 728 |
∴ So the LCM of the given numbers is 2 x 199 x 728 = 289744
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 12/289744
Therefore, the GCF of Fractions 4092/398,1920/1456 is 12/289744
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 398,1456 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(398,1456) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(398,1456) x common factors =2 x 1 = 2
LCM(398,1456) = ( 398 × 1456 ) / 2
LCM(398,1456) = 579488 / 2
LCM(398,1456) = 289744
