So the greatest common factor 328,324 is 4.
Lets's calculate LCM of 687,120
3 | 687, 120 |
229, 40 |
∴ So the LCM of the given numbers is 3 x 229 x 40 = 27480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/27480
Therefore, the GCF of Fractions 328/687,324/120 is 4/27480
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 687,120 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(687,120) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(687,120) x common factors =3 x 1 = 3
LCM(687,120) = ( 687 × 120 ) / 3
LCM(687,120) = 82440 / 3
LCM(687,120) = 27480
