Lets's calculate LCM of 68,7930
2 | 68, 7930 |
34, 3965 |
∴ So the LCM of the given numbers is 2 x 34 x 3965 = 269620
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/269620
Therefore, the GCF of Fractions 285/68,234/7930 is 3/269620
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 68,7930 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(68,7930) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(68,7930) x common factors =2 x 1 = 2
LCM(68,7930) = ( 68 × 7930 ) / 2
LCM(68,7930) = 539240 / 2
LCM(68,7930) = 269620
