So the greatest common factor 36,6568 is 4.
Lets's calculate LCM of 978,1989
3 | 978, 1989 |
326, 663 |
∴ So the LCM of the given numbers is 3 x 326 x 663 = 648414
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/648414
Therefore, the GCF of Fractions 36/978,6568/1989 is 4/648414
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 978,1989 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(978,1989) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(978,1989) x common factors =3 x 1 = 3
LCM(978,1989) = ( 978 × 1989 ) / 3
LCM(978,1989) = 1945242 / 3
LCM(978,1989) = 648414
