So the greatest common factor 432,765 is 9.
Lets's calculate LCM of 282,189
3 | 282, 189 |
94, 63 |
∴ So the LCM of the given numbers is 3 x 94 x 63 = 17766
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/17766
Therefore, the GCF of Fractions 432/282,765/189 is 9/17766
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 282,189 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(282,189) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(282,189) x common factors =3 x 1 = 3
LCM(282,189) = ( 282 × 189 ) / 3
LCM(282,189) = 53298 / 3
LCM(282,189) = 17766
