Greatest Common Factor
We found the factors 873,331 . The biggest common factor number is the GCF number.
So the greatest common factor 873,331 is 1.
Lets's calculate LCM of 123,285
3 | 123, 285 |
41, 95 |
∴ So the LCM of the given numbers is 3 x 41 x 95 = 11685
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/11685
Therefore, the GCF of Fractions 873/123,331/285 is 1/11685
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 123,285 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(123,285) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(123,285) x common factors =3 x 1 = 3
LCM(123,285) = ( 123 × 285 ) / 3
LCM(123,285) = 35055 / 3
LCM(123,285) = 11685
