Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 105/25,492/4959
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 105,492
Greatest Common Factor of Numerators i.e. GCF of 105,492 is 3 .
LCM of Denominators means LCM of 25,4959 as per the given fractions.
LCM of 25,4959 is 123975 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 105,492
3 | 105, 492 |
35, 164 |
∴ So the GCF of the given numbers is 3 = 3

Factors of 492
List of positive integer factors of 492 that divides 492 without a remainder.
1,2,3,4,6,12,41,82,123,164,246,492
Greatest Common Factor
We found the factors 105,492 . The biggest common factor number is the GCF number.
So the greatest common factor 105,492 is 3.
Lets's calculate LCM of 25,4959
Given numbers has no common factors except 1. So, there LCM is their product i.e 123975
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/123975
Therefore, the GCF of Fractions 105/25,492/4959 is 3/123975
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 25,4959 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(25,4959) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(25,4959) x common factors =1 x 1 = 1
LCM(25,4959) = ( 25 × 4959 ) / 1
LCM(25,4959) = 123975 / 1
LCM(25,4959) = 123975
