Lets's calculate LCM of 645,905
5 | 645, 905 |
129, 181 |
∴ So the LCM of the given numbers is 5 x 129 x 181 = 116745
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/116745
Therefore, the GCF of Fractions 206/645,968/905 is 2/116745
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 645,905 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(645,905) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(645,905) x common factors =5 x 1 = 5
LCM(645,905) = ( 645 × 905 ) / 5
LCM(645,905) = 583725 / 5
LCM(645,905) = 116745
