Lets's calculate LCM of 298,826
2 | 298, 826 |
149, 413 |
∴ So the LCM of the given numbers is 2 x 149 x 413 = 123074
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 384/123074
Therefore, the GCF of Fractions 768/298,384/826 is 384/123074
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 298,826 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(298,826) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(298,826) x common factors =2 x 1 = 2
LCM(298,826) = ( 298 × 826 ) / 2
LCM(298,826) = 246148 / 2
LCM(298,826) = 123074
