Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 168/412,785/686
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 168,785
Greatest Common Factor of Numerators i.e. GCF of 168,785 is 1 .
LCM of Denominators means LCM of 412,686 as per the given fractions.
LCM of 412,686 is 141316 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 168,785
∴ So GCF of numbers is 1 because of no common factors present between them.

Factors of 785
List of positive integer factors of 785 that divides 785 without a remainder.
1,5,157,785
Greatest Common Factor
We found the factors 168,785 . The biggest common factor number is the GCF number.
So the greatest common factor 168,785 is 1.
Lets's calculate LCM of 412,686
2 | 412, 686 |
206, 343 |
∴ So the LCM of the given numbers is 2 x 206 x 343 = 141316
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/141316
Therefore, the GCF of Fractions 168/412,785/686 is 1/141316
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 412,686 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(412,686) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(412,686) x common factors =2 x 1 = 2
LCM(412,686) = ( 412 × 686 ) / 2
LCM(412,686) = 282632 / 2
LCM(412,686) = 141316
