We found the factors 603,684 . The biggest common factor number is the GCF number.
So the greatest common factor 603,684 is 9.
Lets's calculate LCM of 12,393
3 | 12, 393 |
4, 131 |
∴ So the LCM of the given numbers is 3 x 4 x 131 = 1572
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/1572
Therefore, the GCF of Fractions 603/12,684/393 is 9/1572
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 12,393 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(12,393) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(12,393) x common factors =3 x 1 = 3
LCM(12,393) = ( 12 × 393 ) / 3
LCM(12,393) = 4716 / 3
LCM(12,393) = 1572
