So the greatest common factor 315,513 is 9.
Lets's calculate LCM of 510,339
3 | 510, 339 |
170, 113 |
∴ So the LCM of the given numbers is 3 x 170 x 113 = 57630
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/57630
Therefore, the GCF of Fractions 315/510,513/339 is 9/57630
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 510,339 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(510,339) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(510,339) x common factors =3 x 1 = 3
LCM(510,339) = ( 510 × 339 ) / 3
LCM(510,339) = 172890 / 3
LCM(510,339) = 57630
