Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 640/825,831/287
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 640,831
Greatest Common Factor of Numerators i.e. GCF of 640,831 is 1 .
LCM of Denominators means LCM of 825,287 as per the given fractions.
LCM of 825,287 is 236775 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 640,831
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 640 that divides 640 without a remainder.
1,2,4,5,8,10,16,20,32,40,64,80,128,160,320,640
Factors of 831
List of positive integer factors of 831 that divides 831 without a remainder.
1,3,277,831
Greatest Common Factor
We found the factors 640,831 . The biggest common factor number is the GCF number.
So the greatest common factor 640,831 is 1.
Lets's calculate LCM of 825,287
Given numbers has no common factors except 1. So, there LCM is their product i.e 236775
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/236775
Therefore, the GCF of Fractions 640/825,831/287 is 1/236775
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 825,287 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(825,287) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(825,287) x common factors =1 x 1 = 1
LCM(825,287) = ( 825 × 287 ) / 1
LCM(825,287) = 236775 / 1
LCM(825,287) = 236775
