Lets's calculate LCM of 417,789
3 | 417, 789 |
139, 263 |
∴ So the LCM of the given numbers is 3 x 139 x 263 = 109671
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/109671
Therefore, the GCF of Fractions 2472/417,8402/789 is 2/109671
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 417,789 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(417,789) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(417,789) x common factors =3 x 1 = 3
LCM(417,789) = ( 417 × 789 ) / 3
LCM(417,789) = 329013 / 3
LCM(417,789) = 109671
