Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 172/739,1672/868
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 172,1672
Greatest Common Factor of Numerators i.e. GCF of 172,1672 is 4 .
LCM of Denominators means LCM of 739,868 as per the given fractions.
LCM of 739,868 is 641452 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 172,1672
2 | 172, 1672 |
2 | 86, 836 |
43, 418 |
∴ So the GCF of the given numbers is 2 x 2 = 4

Factors of 1672
List of positive integer factors of 1672 that divides 1672 without a remainder.
1,2,4,8,11,19,22,38,44,76,88,152,209,418,836,1672
Greatest Common Factor
We found the factors 172,1672 . The biggest common factor number is the GCF number.
So the greatest common factor 172,1672 is 4.
Lets's calculate LCM of 739,868
Given numbers has no common factors except 1. So, there LCM is their product i.e 641452
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/641452
Therefore, the GCF of Fractions 172/739,1672/868 is 4/641452
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 739,868 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(739,868) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(739,868) x common factors =1 x 1 = 1
LCM(739,868) = ( 739 × 868 ) / 1
LCM(739,868) = 641452 / 1
LCM(739,868) = 641452
Here are some samples of GCF of Fractions calculations.
