Greatest Common Factor
We found the factors 19,81,458 . The biggest common factor number is the GCF number.
So the greatest common factor 19,81,458 is 1.
Lets's calculate LCM of 686,905,445
5 | 686, 905, 445 |
686, 181, 89 |
∴ So the LCM of the given numbers is 5 x 686 x 181 x 89 = 55253870
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/55253870
Therefore, the GCF of Fractions 19/686,81/905,458/445 is 1/55253870
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 686,905,445 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(686,905,445) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(686,905,445) x common factors =1 x 5 = 5
LCM(686,905,445) = ( 686 × 905 × 445 ) / 5
LCM(686,905,445) = 276269350 / 5
LCM(686,905,445) = 55253870
