Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 278/72,126/3191
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 278,126
Greatest Common Factor of Numerators i.e. GCF of 278,126 is 2 .
LCM of Denominators means LCM of 72,3191 as per the given fractions.
LCM of 72,3191 is 229752 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 278,126
2 | 278, 126 |
139, 63 |
∴ So the GCF of the given numbers is 2 = 2

List of positive integer factors of 278 that divides 278 without a remainder.
1,2,139,278
Factors of 126
List of positive integer factors of 126 that divides 126 without a remainder.
1,2,3,6,7,9,14,18,21,42,63,126
Greatest Common Factor
We found the factors 278,126 . The biggest common factor number is the GCF number.
So the greatest common factor 278,126 is 2.
Lets's calculate LCM of 72,3191
Given numbers has no common factors except 1. So, there LCM is their product i.e 229752
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/229752
Therefore, the GCF of Fractions 278/72,126/3191 is 2/229752
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 72,3191 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(72,3191) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(72,3191) x common factors =1 x 1 = 1
LCM(72,3191) = ( 72 × 3191 ) / 1
LCM(72,3191) = 229752 / 1
LCM(72,3191) = 229752
Here are some samples of GCF of Fractions calculations.
