We found the factors 225,210 . The biggest common factor number is the GCF number.
So the greatest common factor 225,210 is 15.
Lets's calculate LCM of 402,684
2 | 402, 684 |
3 | 201, 342 |
67, 114 |
∴ So the LCM of the given numbers is 2 x 3 x 67 x 114 = 45828
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/45828
Therefore, the GCF of Fractions 225/402,210/684 is 15/45828
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 402,684 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(402,684) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(402,684) x common factors =6 x 1 = 6
LCM(402,684) = ( 402 × 684 ) / 6
LCM(402,684) = 274968 / 6
LCM(402,684) = 45828
