Greatest Common Factor
We found the factors 619,489 . The biggest common factor number is the GCF number.
So the greatest common factor 619,489 is 1.
Lets's calculate LCM of 15,861
3 | 15, 861 |
5, 287 |
∴ So the LCM of the given numbers is 3 x 5 x 287 = 4305
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4305
Therefore, the GCF of Fractions 619/15,489/861 is 1/4305
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 15,861 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,861) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(15,861) x common factors =3 x 1 = 3
LCM(15,861) = ( 15 × 861 ) / 3
LCM(15,861) = 12915 / 3
LCM(15,861) = 4305
