So the greatest common factor 380,711 is 1.
Lets's calculate LCM of 309,621
3 | 309, 621 |
103, 207 |
∴ So the LCM of the given numbers is 3 x 103 x 207 = 63963
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/63963
Therefore, the GCF of Fractions 380/309,711/621 is 1/63963
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 309,621 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(309,621) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(309,621) x common factors =3 x 1 = 3
LCM(309,621) = ( 309 × 621 ) / 3
LCM(309,621) = 191889 / 3
LCM(309,621) = 63963
