Lets's calculate LCM of 414,9966
2 | 414, 9966 |
3 | 207, 4983 |
69, 1661 |
∴ So the LCM of the given numbers is 2 x 3 x 69 x 1661 = 687654
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/687654
Therefore, the GCF of Fractions 338/414,7917/9966 is 13/687654
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 414,9966 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(414,9966) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(414,9966) x common factors =6 x 1 = 6
LCM(414,9966) = ( 414 × 9966 ) / 6
LCM(414,9966) = 4125924 / 6
LCM(414,9966) = 687654
