Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 275/254,835/728
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 275,835
Greatest Common Factor of Numerators i.e. GCF of 275,835 is 5 .
LCM of Denominators means LCM of 254,728 as per the given fractions.
LCM of 254,728 is 92456 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 275,835
5 | 275, 835 |
55, 167 |
∴ So the GCF of the given numbers is 5 = 5

Factors of 835
List of positive integer factors of 835 that divides 835 without a remainder.
1,5,167,835
Greatest Common Factor
We found the factors 275,835 . The biggest common factor number is the GCF number.
So the greatest common factor 275,835 is 5.
Lets's calculate LCM of 254,728
2 | 254, 728 |
127, 364 |
∴ So the LCM of the given numbers is 2 x 127 x 364 = 92456
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/92456
Therefore, the GCF of Fractions 275/254,835/728 is 5/92456
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 254,728 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(254,728) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(254,728) x common factors =2 x 1 = 2
LCM(254,728) = ( 254 × 728 ) / 2
LCM(254,728) = 184912 / 2
LCM(254,728) = 92456
