:1,2,3,4,6,7,8,12,14,16,21,24,28,32,42,48,56,84,96,112,168,224,336,672
Greatest Common Factor
We found the factors 504,672 . The biggest common factor number is the GCF number.
So the greatest common factor 504,672 is 168.
Lets's calculate LCM of 643,104
Given numbers has no common factors except 1. So, there LCM is their product i.e 66872
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 168/66872
Therefore, the GCF of Fractions 504/643,672/104 is 168/66872
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 643,104 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(643,104) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(643,104) x common factors =1 x 1 = 1
LCM(643,104) = ( 643 × 104 ) / 1
LCM(643,104) = 66872 / 1
LCM(643,104) = 66872
