So the greatest common factor 658,1128 is 94.
Lets's calculate LCM of 204,666
2 | 204, 666 |
3 | 102, 333 |
34, 111 |
∴ So the LCM of the given numbers is 2 x 3 x 34 x 111 = 22644
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 94/22644
Therefore, the GCF of Fractions 658/204,1128/666 is 94/22644
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 204,666 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(204,666) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(204,666) x common factors =6 x 1 = 6
LCM(204,666) = ( 204 × 666 ) / 6
LCM(204,666) = 135864 / 6
LCM(204,666) = 22644
