Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 302/407,808/472
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 302,808
Greatest Common Factor of Numerators i.e. GCF of 302,808 is 2 .
LCM of Denominators means LCM of 407,472 as per the given fractions.
LCM of 407,472 is 192104 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 302,808
2 | 302, 808 |
151, 404 |
∴ So the GCF of the given numbers is 2 = 2

List of positive integer factors of 302 that divides 302 without a remainder.
1,2,151,302
Factors of 808
List of positive integer factors of 808 that divides 808 without a remainder.
1,2,4,8,101,202,404,808
Greatest Common Factor
We found the factors 302,808 . The biggest common factor number is the GCF number.
So the greatest common factor 302,808 is 2.
Lets's calculate LCM of 407,472
Given numbers has no common factors except 1. So, there LCM is their product i.e 192104
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/192104
Therefore, the GCF of Fractions 302/407,808/472 is 2/192104
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 407,472 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(407,472) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(407,472) x common factors =1 x 1 = 1
LCM(407,472) = ( 407 × 472 ) / 1
LCM(407,472) = 192104 / 1
LCM(407,472) = 192104
Here are some samples of GCF of Fractions calculations.
