Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 130/490,155/363
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 130,155
Greatest Common Factor of Numerators i.e. GCF of 130,155 is 5 .
LCM of Denominators means LCM of 490,363 as per the given fractions.
LCM of 490,363 is 177870 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 130,155
5 | 130, 155 |
26, 31 |
∴ So the GCF of the given numbers is 5 = 5

List of positive integer factors of 130 that divides 130 without a remainder.
1,2,5,10,13,26,65,130
Factors of 155
List of positive integer factors of 155 that divides 155 without a remainder.
1,5,31,155
Greatest Common Factor
We found the factors 130,155 . The biggest common factor number is the GCF number.
So the greatest common factor 130,155 is 5.
Lets's calculate LCM of 490,363
Given numbers has no common factors except 1. So, there LCM is their product i.e 177870
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/177870
Therefore, the GCF of Fractions 130/490,155/363 is 5/177870
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 490,363 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(490,363) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(490,363) x common factors =1 x 1 = 1
LCM(490,363) = ( 490 × 363 ) / 1
LCM(490,363) = 177870 / 1
LCM(490,363) = 177870
Here are some samples of GCF of Fractions calculations.
