Greatest Common Factor
We found the factors 80,30,653 . The biggest common factor number is the GCF number.
So the greatest common factor 80,30,653 is 1.
Lets's calculate LCM of 867,390,923
3 | 867, 390, 923 |
13 | 289, 130, 923 |
289, 10, 71 |
∴ So the LCM of the given numbers is 3 x 13 x 289 x 10 x 71 = 8002410
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/8002410
Therefore, the GCF of Fractions 80/867,30/390,653/923 is 1/8002410
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 867,390,923 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(867,390,923) = 1
common factors(in case of two or more numbers have common factors) = 39
GCF(867,390,923) x common factors =1 x 39 = 39
LCM(867,390,923) = ( 867 × 390 × 923 ) / 39
LCM(867,390,923) = 312093990 / 39
LCM(867,390,923) = 8002410
