Greatest Common Factor
We found the factors 30,70,622 . The biggest common factor number is the GCF number.
So the greatest common factor 30,70,622 is 2.
Lets's calculate LCM of 868,214,830
2 | 868, 214, 830 |
434, 107, 415 |
∴ So the LCM of the given numbers is 2 x 434 x 107 x 415 = 38543540
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/38543540
Therefore, the GCF of Fractions 30/868,70/214,622/830 is 2/38543540
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 868,214,830 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(868,214,830) = 2
common factors(in case of two or more numbers have common factors) = 2
GCF(868,214,830) x common factors =2 x 2 = 4
LCM(868,214,830) = ( 868 × 214 × 830 ) / 4
LCM(868,214,830) = 154174160 / 4
LCM(868,214,830) = 38543540
