Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 643/259,1550/103
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 643,1550
Greatest Common Factor of Numerators i.e. GCF of 643,1550 is 1 .
LCM of Denominators means LCM of 259,103 as per the given fractions.
LCM of 259,103 is 26677 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 643,1550
∴ So GCF of numbers is 1 because of no common factors present between them.

1,643
Factors of 1550
List of positive integer factors of 1550 that divides 1550 without a remainder.
1,2,5,10,25,31,50,62,155,310,775,1550
Greatest Common Factor
We found the factors 643,1550 . The biggest common factor number is the GCF number.
So the greatest common factor 643,1550 is 1.
Lets's calculate LCM of 259,103
Given numbers has no common factors except 1. So, there LCM is their product i.e 26677
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/26677
Therefore, the GCF of Fractions 643/259,1550/103 is 1/26677
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 259,103 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(259,103) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(259,103) x common factors =1 x 1 = 1
LCM(259,103) = ( 259 × 103 ) / 1
LCM(259,103) = 26677 / 1
LCM(259,103) = 26677
Here are some samples of GCF of Fractions calculations.
