Greatest Common Factor
We found the factors 687,949 . The biggest common factor number is the GCF number.
So the greatest common factor 687,949 is 1.
Lets's calculate LCM of 15,848
Given numbers has no common factors except 1. So, there LCM is their product i.e 12720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/12720
Therefore, the GCF of Fractions 687/15,949/848 is 1/12720
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 15,848 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,848) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(15,848) x common factors =1 x 1 = 1
LCM(15,848) = ( 15 × 848 ) / 1
LCM(15,848) = 12720 / 1
LCM(15,848) = 12720
