Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 620/486,860/151
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 620,860
Greatest Common Factor of Numerators i.e. GCF of 620,860 is 20 .
LCM of Denominators means LCM of 486,151 as per the given fractions.
LCM of 486,151 is 73386 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 620,860
2 | 620, 860 |
2 | 310, 430 |
5 | 155, 215 |
31, 43 |
∴ So the GCF of the given numbers is 2 x 2 x 5 = 20

Factors of 860
List of positive integer factors of 860 that divides 860 without a remainder.
1,2,4,5,10,20,43,86,172,215,430,860
Greatest Common Factor
We found the factors 620,860 . The biggest common factor number is the GCF number.
So the greatest common factor 620,860 is 20.
Lets's calculate LCM of 486,151
Given numbers has no common factors except 1. So, there LCM is their product i.e 73386
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/73386
Therefore, the GCF of Fractions 620/486,860/151 is 20/73386
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 486,151 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(486,151) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(486,151) x common factors =1 x 1 = 1
LCM(486,151) = ( 486 × 151 ) / 1
LCM(486,151) = 73386 / 1
LCM(486,151) = 73386
Here are some samples of GCF of Fractions calculations.
