Greatest Common Factor
We found the factors 85,438,631 . The biggest common factor number is the GCF number.
So the greatest common factor 85,438,631 is 1.
Lets's calculate LCM of 70,13,734
2 | 70, 13, 734 |
35, 13, 367 |
∴ So the LCM of the given numbers is 2 x 35 x 13 x 367 = 333970
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/333970
Therefore, the GCF of Fractions 85/70,438/13,631/734 is 1/333970
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 70,13,734 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,13,734) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(70,13,734) x common factors =1 x 2 = 2
LCM(70,13,734) = ( 70 × 13 × 734 ) / 2
LCM(70,13,734) = 667940 / 2
LCM(70,13,734) = 333970
