Greatest Common Factor
We found the factors 381,477,819 . The biggest common factor number is the GCF number.
So the greatest common factor 381,477,819 is 3.
Lets's calculate LCM of 55,13,956
Given numbers has no common factors except 1. So, there LCM is their product i.e 683540
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/683540
Therefore, the GCF of Fractions 381/55,477/13,819/956 is 3/683540
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 55,13,956 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(55,13,956) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(55,13,956) x common factors =1 x 1 = 1
LCM(55,13,956) = ( 55 × 13 × 956 ) / 1
LCM(55,13,956) = 683540 / 1
LCM(55,13,956) = 683540
Here are some samples of GCF of Fractions calculations.
