Lets's calculate LCM of 315,9705
3 | 315, 9705 |
5 | 105, 3235 |
21, 647 |
∴ So the LCM of the given numbers is 3 x 5 x 21 x 647 = 203805
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/203805
Therefore, the GCF of Fractions 268/315,4490/9705 is 2/203805
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 315,9705 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(315,9705) = 15
common factors(in case of two or more numbers have common factors) = 1
GCF(315,9705) x common factors =15 x 1 = 15
LCM(315,9705) = ( 315 × 9705 ) / 15
LCM(315,9705) = 3057075 / 15
LCM(315,9705) = 203805
