So the greatest common factor 852,756 is 12.
Lets's calculate LCM of 168,717
3 | 168, 717 |
56, 239 |
∴ So the LCM of the given numbers is 3 x 56 x 239 = 40152
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 12/40152
Therefore, the GCF of Fractions 852/168,756/717 is 12/40152
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 168,717 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(168,717) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(168,717) x common factors =3 x 1 = 3
LCM(168,717) = ( 168 × 717 ) / 3
LCM(168,717) = 120456 / 3
LCM(168,717) = 40152
