Factors of 6459
List of positive integer factors of 6459 that divides 6459 without a remainder.
1,3,2153,6459
Greatest Common Factor
We found the factors 459,6459 . The biggest common factor number is the GCF number.
So the greatest common factor 459,6459 is 3.
Lets's calculate LCM of 421,320
Given numbers has no common factors except 1. So, there LCM is their product i.e 134720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/134720
Therefore, the GCF of Fractions 459/421,6459/320 is 3/134720
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 421,320 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(421,320) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(421,320) x common factors =1 x 1 = 1
LCM(421,320) = ( 421 × 320 ) / 1
LCM(421,320) = 134720 / 1
LCM(421,320) = 134720
Here are some samples of GCF of Fractions calculations.
