We found the factors 438,756 . The biggest common factor number is the GCF number.
So the greatest common factor 438,756 is 6.
Lets's calculate LCM of 2557,1245
Given numbers has no common factors except 1. So, there LCM is their product i.e 3183465
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/3183465
Therefore, the GCF of Fractions 438/2557,756/1245 is 6/3183465
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 2557,1245 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(2557,1245) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(2557,1245) x common factors =1 x 1 = 1
LCM(2557,1245) = ( 2557 × 1245 ) / 1
LCM(2557,1245) = 3183465 / 1
LCM(2557,1245) = 3183465
Here are some samples of GCF of Fractions calculations.
