1,227
Greatest Common Factor
We found the factors 240,258,227 . The biggest common factor number is the GCF number.
So the greatest common factor 240,258,227 is 1.
Lets's calculate LCM of 640,530,870
2 | 640, 530, 870 |
5 | 320, 265, 435 |
64, 53, 87 |
∴ So the LCM of the given numbers is 2 x 5 x 64 x 53 x 87 = 2951040
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2951040
Therefore, the GCF of Fractions 240/640,258/530,227/870 is 1/2951040
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 640,530,870 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(640,530,870) = 10
common factors(in case of two or more numbers have common factors) = 10
GCF(640,530,870) x common factors =10 x 10 = 100
LCM(640,530,870) = ( 640 × 530 × 870 ) / 100
LCM(640,530,870) = 295104000 / 100
LCM(640,530,870) = 2951040
