Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 20/251,240/593
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 20,240
Greatest Common Factor of Numerators i.e. GCF of 20,240 is 20 .
LCM of Denominators means LCM of 251,593 as per the given fractions.
LCM of 251,593 is 148843 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 20,240
2 | 20, 240 |
2 | 10, 120 |
5 | 5, 60 |
1, 12 |
∴ So the GCF of the given numbers is 2 x 2 x 5 = 20

1,2,4,5,10,20
Factors of 240
List of positive integer factors of 240 that divides 240 without a remainder.
1,2,3,4,5,6,8,10,12,15,16,20,24,30,40,48,60,80,120,240
Greatest Common Factor
We found the factors 20,240 . The biggest common factor number is the GCF number.
So the greatest common factor 20,240 is 20.
Lets's calculate LCM of 251,593
Given numbers has no common factors except 1. So, there LCM is their product i.e 148843
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/148843
Therefore, the GCF of Fractions 20/251,240/593 is 20/148843
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 251,593 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(251,593) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(251,593) x common factors =1 x 1 = 1
LCM(251,593) = ( 251 × 593 ) / 1
LCM(251,593) = 148843 / 1
LCM(251,593) = 148843
Here are some samples of GCF of Fractions calculations.
