Lets's calculate LCM of 307,921,208
307 | 307, 921, 208 |
1, 3, 208 |
∴ So the LCM of the given numbers is 307 x 1 x 3 x 208 = 191568
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/191568
Therefore, the GCF of Fractions 47/307,969/921,343/208 is 1/191568
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 307,921,208 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(307,921,208) = 1
common factors(in case of two or more numbers have common factors) = 307
GCF(307,921,208) x common factors =1 x 307 = 307
LCM(307,921,208) = ( 307 × 921 × 208 ) / 307
LCM(307,921,208) = 58811376 / 307
LCM(307,921,208) = 191568
