Lets's calculate LCM of 663,355,238
17 | 663, 355, 238 |
39, 355, 14 |
∴ So the LCM of the given numbers is 17 x 39 x 355 x 14 = 3295110
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/3295110
Therefore, the GCF of Fractions 66/663,66/355,121/238 is 11/3295110
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 663,355,238 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(663,355,238) = 1
common factors(in case of two or more numbers have common factors) = 17
GCF(663,355,238) x common factors =1 x 17 = 17
LCM(663,355,238) = ( 663 × 355 × 238 ) / 17
LCM(663,355,238) = 56016870 / 17
LCM(663,355,238) = 3295110
