Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 180/25,120/351
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 180,120
Greatest Common Factor of Numerators i.e. GCF of 180,120 is 60 .
LCM of Denominators means LCM of 25,351 as per the given fractions.
LCM of 25,351 is 8775 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 180,120
2 | 180, 120 |
2 | 90, 60 |
3 | 45, 30 |
5 | 15, 10 |
3, 2 |
∴ So the GCF of the given numbers is 2 x 2 x 3 x 5 = 60

Factors of 120
List of positive integer factors of 120 that divides 120 without a remainder.
1,2,3,4,5,6,8,10,12,15,20,24,30,40,60,120
Greatest Common Factor
We found the factors 180,120 . The biggest common factor number is the GCF number.
So the greatest common factor 180,120 is 60.
Lets's calculate LCM of 25,351
Given numbers has no common factors except 1. So, there LCM is their product i.e 8775
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 60/8775
Therefore, the GCF of Fractions 180/25,120/351 is 60/8775
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 25,351 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(25,351) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(25,351) x common factors =1 x 1 = 1
LCM(25,351) = ( 25 × 351 ) / 1
LCM(25,351) = 8775 / 1
LCM(25,351) = 8775
Here are some samples of GCF of Fractions calculations.
