So the greatest common factor 342,768 is 6.
Lets's calculate LCM of 666,916
2 | 666, 916 |
333, 458 |
∴ So the LCM of the given numbers is 2 x 333 x 458 = 305028
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/305028
Therefore, the GCF of Fractions 342/666,768/916 is 6/305028
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 666,916 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(666,916) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(666,916) x common factors =2 x 1 = 2
LCM(666,916) = ( 666 × 916 ) / 2
LCM(666,916) = 610056 / 2
LCM(666,916) = 305028
