Greatest Common Factor
We found the factors 1000,1440 . The biggest common factor number is the GCF number.
So the greatest common factor 1000,1440 is 40.
Lets's calculate LCM of 288,864
2 | 288, 864 |
2 | 144, 432 |
2 | 72, 216 |
2 | 36, 108 |
2 | 18, 54 |
3 | 9, 27 |
3 | 3, 9 |
1, 3 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 2 x 3 x 3 x 1 x 3 = 864
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 40/864
Therefore, the GCF of Fractions 1000/288,1440/864 is 40/864
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 288,864 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(288,864) = 288
common factors(in case of two or more numbers have common factors) = 1
GCF(288,864) x common factors =288 x 1 = 288
LCM(288,864) = ( 288 × 864 ) / 288
LCM(288,864) = 248832 / 288
LCM(288,864) = 864
