:1,2,4,5,10,19,20,38,76,95,190,380
Greatest Common Factor
We found the factors 580,380 . The biggest common factor number is the GCF number.
So the greatest common factor 580,380 is 20.
Lets's calculate LCM of 954,921
3 | 954, 921 |
318, 307 |
∴ So the LCM of the given numbers is 3 x 318 x 307 = 292878
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/292878
Therefore, the GCF of Fractions 580/954,380/921 is 20/292878
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 954,921 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(954,921) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(954,921) x common factors =3 x 1 = 3
LCM(954,921) = ( 954 × 921 ) / 3
LCM(954,921) = 878634 / 3
LCM(954,921) = 292878
