Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 42/263,875/487
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 42,875
Greatest Common Factor of Numerators i.e. GCF of 42,875 is 7 .
LCM of Denominators means LCM of 263,487 as per the given fractions.
LCM of 263,487 is 128081 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 42,875
7 | 42, 875 |
6, 125 |
∴ So the GCF of the given numbers is 7 = 7

List of positive integer factors of 42 that divides 42 without a remainder.
1,2,3,6,7,14,21,42
Factors of 875
List of positive integer factors of 875 that divides 875 without a remainder.
1,5,7,25,35,125,175,875
Greatest Common Factor
We found the factors 42,875 . The biggest common factor number is the GCF number.
So the greatest common factor 42,875 is 7.
Lets's calculate LCM of 263,487
Given numbers has no common factors except 1. So, there LCM is their product i.e 128081
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/128081
Therefore, the GCF of Fractions 42/263,875/487 is 7/128081
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 263,487 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(263,487) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(263,487) x common factors =1 x 1 = 1
LCM(263,487) = ( 263 × 487 ) / 1
LCM(263,487) = 128081 / 1
LCM(263,487) = 128081
