Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 123/633,3642/781
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 123,3642
Greatest Common Factor of Numerators i.e. GCF of 123,3642 is 3 .
LCM of Denominators means LCM of 633,781 as per the given fractions.
LCM of 633,781 is 494373 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 123,3642
3 | 123, 3642 |
41, 1214 |
∴ So the GCF of the given numbers is 3 = 3

1,2,3,6,607,1214,1821,3642
Greatest Common Factor
We found the factors 123,3642 . The biggest common factor number is the GCF number.
So the greatest common factor 123,3642 is 3.
Lets's calculate LCM of 633,781
Given numbers has no common factors except 1. So, there LCM is their product i.e 494373
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/494373
Therefore, the GCF of Fractions 123/633,3642/781 is 3/494373
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 633,781 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(633,781) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(633,781) x common factors =1 x 1 = 1
LCM(633,781) = ( 633 × 781 ) / 1
LCM(633,781) = 494373 / 1
LCM(633,781) = 494373
Here are some samples of GCF of Fractions calculations.
