Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 801/818,1400/487
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 801,1400
Greatest Common Factor of Numerators i.e. GCF of 801,1400 is 1 .
LCM of Denominators means LCM of 818,487 as per the given fractions.
LCM of 818,487 is 398366 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 801,1400
∴ So GCF of numbers is 1 because of no common factors present between them.

Factors of 1400
List of positive integer factors of 1400 that divides 1400 without a remainder.
1,2,4,5,7,8,10,14,20,25,28,35,40,50,56,70,100,140,175,200,280,350,700,1400
Greatest Common Factor
We found the factors 801,1400 . The biggest common factor number is the GCF number.
So the greatest common factor 801,1400 is 1.
Lets's calculate LCM of 818,487
Given numbers has no common factors except 1. So, there LCM is their product i.e 398366
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/398366
Therefore, the GCF of Fractions 801/818,1400/487 is 1/398366
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 818,487 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(818,487) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(818,487) x common factors =1 x 1 = 1
LCM(818,487) = ( 818 × 487 ) / 1
LCM(818,487) = 398366 / 1
LCM(818,487) = 398366
Here are some samples of GCF of Fractions calculations.
