Lets's calculate LCM of 441,978
3 | 441, 978 |
147, 326 |
∴ So the LCM of the given numbers is 3 x 147 x 326 = 143766
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/143766
Therefore, the GCF of Fractions 7978/441,2776/978 is 2/143766
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 441,978 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(441,978) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(441,978) x common factors =3 x 1 = 3
LCM(441,978) = ( 441 × 978 ) / 3
LCM(441,978) = 431298 / 3
LCM(441,978) = 143766
