Lets's calculate LCM of 206,844
2 | 206, 844 |
103, 422 |
∴ So the LCM of the given numbers is 2 x 103 x 422 = 86932
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/86932
Therefore, the GCF of Fractions 1970/206,7171/844 is 1/86932
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 206,844 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(206,844) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(206,844) x common factors =2 x 1 = 2
LCM(206,844) = ( 206 × 844 ) / 2
LCM(206,844) = 173864 / 2
LCM(206,844) = 86932
