Lets's calculate LCM of 867,7518
3 | 867, 7518 |
289, 2506 |
∴ So the LCM of the given numbers is 3 x 289 x 2506 = 2172702
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 8/2172702
Therefore, the GCF of Fractions 1688/867,2872/7518 is 8/2172702
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 867,7518 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(867,7518) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(867,7518) x common factors =3 x 1 = 3
LCM(867,7518) = ( 867 × 7518 ) / 3
LCM(867,7518) = 6518106 / 3
LCM(867,7518) = 2172702
