Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 644/644,449/857
Formula to find GCF of Fractions is
GCF = GCF of Numerators/LCM of Denominators
As per the formula GCF of Fractions let’s split into two parts and find the GCF of Numerators and LCM of Denominators
In the given fractions GCF of Numerators means GCF of 644,449
Greatest Common Factor of Numerators i.e. GCF of 644,449 is 1 .
LCM of Denominators means LCM of 644,857 as per the given fractions.
LCM of 644,857 is 551908 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 644,449
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 644 that divides 644 without a remainder.
1,2,4,7,14,23,28,46,92,161,322,644
Factors of 449
List of positive integer factors of 449 that divides 449 without a remainder.
1,449
Greatest Common Factor
We found the factors 644,449 . The biggest common factor number is the GCF number.
So the greatest common factor 644,449 is 1.
Lets's calculate LCM of 644,857
Given numbers has no common factors except 1. So, there LCM is their product i.e 551908
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/551908
Therefore, the GCF of Fractions 644/644,449/857 is 1/551908
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 644,857 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(644,857) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(644,857) x common factors =1 x 1 = 1
LCM(644,857) = ( 644 × 857 ) / 1
LCM(644,857) = 551908 / 1
LCM(644,857) = 551908
