Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 814/749,808/905
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 814,808
Greatest Common Factor of Numerators i.e. GCF of 814,808 is 2 .
LCM of Denominators means LCM of 749,905 as per the given fractions.
LCM of 749,905 is 677845 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 814,808
2 | 814, 808 |
407, 404 |
∴ So the GCF of the given numbers is 2 = 2

Factors of 808
List of positive integer factors of 808 that divides 808 without a remainder.
1,2,4,8,101,202,404,808
Greatest Common Factor
We found the factors 814,808 . The biggest common factor number is the GCF number.
So the greatest common factor 814,808 is 2.
Lets's calculate LCM of 749,905
Given numbers has no common factors except 1. So, there LCM is their product i.e 677845
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/677845
Therefore, the GCF of Fractions 814/749,808/905 is 2/677845
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 749,905 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(749,905) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(749,905) x common factors =1 x 1 = 1
LCM(749,905) = ( 749 × 905 ) / 1
LCM(749,905) = 677845 / 1
LCM(749,905) = 677845
Here are some samples of GCF of Fractions calculations.
