Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 170/649,338/195
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 170,338
Greatest Common Factor of Numerators i.e. GCF of 170,338 is 2 .
LCM of Denominators means LCM of 649,195 as per the given fractions.
LCM of 649,195 is 126555 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 170,338
2 | 170, 338 |
85, 169 |
∴ So the GCF of the given numbers is 2 = 2

List of positive integer factors of 170 that divides 170 without a remainder.
1,2,5,10,17,34,85,170
Factors of 338
List of positive integer factors of 338 that divides 338 without a remainder.
1,2,13,26,169,338
Greatest Common Factor
We found the factors 170,338 . The biggest common factor number is the GCF number.
So the greatest common factor 170,338 is 2.
Lets's calculate LCM of 649,195
Given numbers has no common factors except 1. So, there LCM is their product i.e 126555
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/126555
Therefore, the GCF of Fractions 170/649,338/195 is 2/126555
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 649,195 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(649,195) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(649,195) x common factors =1 x 1 = 1
LCM(649,195) = ( 649 × 195 ) / 1
LCM(649,195) = 126555 / 1
LCM(649,195) = 126555
Here are some samples of GCF of Fractions calculations.
