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 636,862
Greatest Common Factor of Numerators i.e. GCF of 636,862 is 2 .
LCM of Denominators means LCM of 170,871 as per the given fractions.
LCM of 170,871 is 148070 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 636,862
2 | 636, 862 |
318, 431 |
∴ So the GCF of the given numbers is 2 = 2

Factors of 862
List of positive integer factors of 862 that divides 862 without a remainder.
1,2,431,862
Greatest Common Factor
We found the factors 636,862 . The biggest common factor number is the GCF number.
So the greatest common factor 636,862 is 2.
Lets's calculate LCM of 170,871
Given numbers has no common factors except 1. So, there LCM is their product i.e 148070
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/148070
Therefore, the GCF of Fractions 636/170,862/871 is 2/148070
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 170,871 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(170,871) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(170,871) x common factors =1 x 1 = 1
LCM(170,871) = ( 170 × 871 ) / 1
LCM(170,871) = 148070 / 1
LCM(170,871) = 148070
Here are some samples of GCF of Fractions calculations.
