Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 447/25,777/809
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 447,777
Greatest Common Factor of Numerators i.e. GCF of 447,777 is 3 .
LCM of Denominators means LCM of 25,809 as per the given fractions.
LCM of 25,809 is 20225 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 447,777
3 | 447, 777 |
149, 259 |
∴ So the GCF of the given numbers is 3 = 3

Factors of 777
List of positive integer factors of 777 that divides 777 without a remainder.
1,3,7,21,37,111,259,777
Greatest Common Factor
We found the factors 447,777 . The biggest common factor number is the GCF number.
So the greatest common factor 447,777 is 3.
Lets's calculate LCM of 25,809
Given numbers has no common factors except 1. So, there LCM is their product i.e 20225
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/20225
Therefore, the GCF of Fractions 447/25,777/809 is 3/20225
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 25,809 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(25,809) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(25,809) x common factors =1 x 1 = 1
LCM(25,809) = ( 25 × 809 ) / 1
LCM(25,809) = 20225 / 1
LCM(25,809) = 20225
