Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 72/234,828/391
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 72,828
Greatest Common Factor of Numerators i.e. GCF of 72,828 is 36 .
LCM of Denominators means LCM of 234,391 as per the given fractions.
LCM of 234,391 is 91494 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 72,828
2 | 72, 828 |
2 | 36, 414 |
3 | 18, 207 |
3 | 6, 69 |
2, 23 |
∴ So the GCF of the given numbers is 2 x 2 x 3 x 3 = 36

1,2,3,4,6,9,12,18,23,36,46,69,92,138,207,276,414,828
Greatest Common Factor
We found the factors 72,828 . The biggest common factor number is the GCF number.
So the greatest common factor 72,828 is 36.
Lets's calculate LCM of 234,391
Given numbers has no common factors except 1. So, there LCM is their product i.e 91494
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 36/91494
Therefore, the GCF of Fractions 72/234,828/391 is 36/91494
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 234,391 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(234,391) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(234,391) x common factors =1 x 1 = 1
LCM(234,391) = ( 234 × 391 ) / 1
LCM(234,391) = 91494 / 1
LCM(234,391) = 91494
Here are some samples of GCF of Fractions calculations.
