Lets's calculate LCM of 792,954
2 | 792, 954 |
3 | 396, 477 |
3 | 132, 159 |
44, 53 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 44 x 53 = 41976
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/41976
Therefore, the GCF of Fractions 649/792,809/954 is 1/41976
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 792,954 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(792,954) = 18
common factors(in case of two or more numbers have common factors) = 1
GCF(792,954) x common factors =18 x 1 = 18
LCM(792,954) = ( 792 × 954 ) / 18
LCM(792,954) = 755568 / 18
LCM(792,954) = 41976
