So the greatest common factor 640,377 is 1.
Lets's calculate LCM of 446,324
2 | 446, 324 |
223, 162 |
∴ So the LCM of the given numbers is 2 x 223 x 162 = 72252
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/72252
Therefore, the GCF of Fractions 640/446,377/324 is 1/72252
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 446,324 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(446,324) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(446,324) x common factors =2 x 1 = 2
LCM(446,324) = ( 446 × 324 ) / 2
LCM(446,324) = 144504 / 2
LCM(446,324) = 72252
