Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 255/17,979/401
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 255,979
Greatest Common Factor of Numerators i.e. GCF of 255,979 is 1 .
LCM of Denominators means LCM of 17,401 as per the given fractions.
LCM of 17,401 is 6817 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 255,979
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 255
List of positive integer factors of 255 that divides 255 without a remainder.
1,3,5,15,17,51,85,255
Factors of 979
List of positive integer factors of 979 that divides 979 without a remainder.
1,11,89,979
Greatest Common Factor
We found the factors 255,979 . The biggest common factor number is the GCF number.
So the greatest common factor 255,979 is 1.
Lets's calculate LCM of 17,401
Given numbers has no common factors except 1. So, there LCM is their product i.e 6817
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6817
Therefore, the GCF of Fractions 255/17,979/401 is 1/6817
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 17,401 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,401) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(17,401) x common factors =1 x 1 = 1
LCM(17,401) = ( 17 × 401 ) / 1
LCM(17,401) = 6817 / 1
LCM(17,401) = 6817
Here are some samples of GCF of Fractions calculations.
