So the greatest common factor 20,131,836 is 1.
Lets's calculate LCM of 921,691,618
3 | 921, 691, 618 |
307, 691, 206 |
∴ So the LCM of the given numbers is 3 x 307 x 691 x 206 = 131100666
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/131100666
Therefore, the GCF of Fractions 20/921,131/691,836/618 is 1/131100666
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 921,691,618 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(921,691,618) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(921,691,618) x common factors =1 x 3 = 3
LCM(921,691,618) = ( 921 × 691 × 618 ) / 3
LCM(921,691,618) = 393301998 / 3
LCM(921,691,618) = 131100666
