Greatest Common Factor
We found the factors 54,138,958 . The biggest common factor number is the GCF number.
So the greatest common factor 54,138,958 is 2.
Lets's calculate LCM of 64,46,127
2 | 64, 46, 127 |
32, 23, 127 |
∴ So the LCM of the given numbers is 2 x 32 x 23 x 127 = 186944
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/186944
Therefore, the GCF of Fractions 54/64,138/46,958/127 is 2/186944
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 64,46,127 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(64,46,127) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(64,46,127) x common factors =1 x 2 = 2
LCM(64,46,127) = ( 64 × 46 × 127 ) / 2
LCM(64,46,127) = 373888 / 2
LCM(64,46,127) = 186944
