So the greatest common factor 330,639 is 3.
Lets's calculate LCM of 189,246
3 | 189, 246 |
63, 82 |
∴ So the LCM of the given numbers is 3 x 63 x 82 = 15498
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/15498
Therefore, the GCF of Fractions 330/189,639/246 is 3/15498
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 189,246 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(189,246) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(189,246) x common factors =3 x 1 = 3
LCM(189,246) = ( 189 × 246 ) / 3
LCM(189,246) = 46494 / 3
LCM(189,246) = 15498
