Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 20/323,880/121
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 20,880
Greatest Common Factor of Numerators i.e. GCF of 20,880 is 20 .
LCM of Denominators means LCM of 323,121 as per the given fractions.
LCM of 323,121 is 39083 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 20,880
2 | 20, 880 |
2 | 10, 440 |
5 | 5, 220 |
1, 44 |
∴ So the GCF of the given numbers is 2 x 2 x 5 = 20
Factors of 20
List of positive integer factors of 20 that divides 20 without a remainder.
1,2,4,5,10,20
Factors of 880
List of positive integer factors of 880 that divides 880 without a remainder.
1,2,4,5,8,10,11,16,20,22,40,44,55,80,88,110,176,220,440,880
Greatest Common Factor
We found the factors 20,880 . The biggest common factor number is the GCF number.
So the greatest common factor 20,880 is 20.
Lets's calculate LCM of 323,121
Given numbers has no common factors except 1. So, there LCM is their product i.e 39083
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/39083
Therefore, the GCF of Fractions 20/323,880/121 is 20/39083
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 323,121 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(323,121) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(323,121) x common factors =1 x 1 = 1
LCM(323,121) = ( 323 × 121 ) / 1
LCM(323,121) = 39083 / 1
LCM(323,121) = 39083
Here are some samples of GCF of Fractions calculations.
