Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 394/870,165/477
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 394,165
Greatest Common Factor of Numerators i.e. GCF of 394,165 is 1 .
LCM of Denominators means LCM of 870,477 as per the given fractions.
LCM of 870,477 is 138330 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 394,165
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 394

1,2,197,394
Factors of 165
List of positive integer factors of 165 that divides 165 without a remainder.
1,3,5,11,15,33,55,165
Greatest Common Factor
We found the factors 394,165 . The biggest common factor number is the GCF number.
So the greatest common factor 394,165 is 1.
Lets's calculate LCM of 870,477
3 | 870, 477 |
290, 159 |
∴ So the LCM of the given numbers is 3 x 290 x 159 = 138330
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/138330
Therefore, the GCF of Fractions 394/870,165/477 is 1/138330
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 870,477 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(870,477) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(870,477) x common factors =3 x 1 = 3
LCM(870,477) = ( 870 × 477 ) / 3
LCM(870,477) = 414990 / 3
LCM(870,477) = 138330
