1,7,103,721
Greatest Common Factor
We found the factors 471,719,721 . The biggest common factor number is the GCF number.
So the greatest common factor 471,719,721 is 1.
Lets's calculate LCM of 19,12,909
3 | 19, 12, 909 |
19, 4, 303 |
∴ So the LCM of the given numbers is 3 x 19 x 4 x 303 = 69084
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/69084
Therefore, the GCF of Fractions 471/19,719/12,721/909 is 1/69084
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 19,12,909 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,12,909) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(19,12,909) x common factors =1 x 3 = 3
LCM(19,12,909) = ( 19 × 12 × 909 ) / 3
LCM(19,12,909) = 207252 / 3
LCM(19,12,909) = 69084
