Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 520/315,903/668
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 520,903
Greatest Common Factor of Numerators i.e. GCF of 520,903 is 1 .
LCM of Denominators means LCM of 315,668 as per the given fractions.
LCM of 315,668 is 210420 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 520,903
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 520
List of positive integer factors of 520 that divides 520 without a remainder.
1,2,4,5,8,10,13,20,26,40,52,65,104,130,260,520
Factors of 903
List of positive integer factors of 903 that divides 903 without a remainder.
1,3,7,21,43,129,301,903
Greatest Common Factor
We found the factors 520,903 . The biggest common factor number is the GCF number.
So the greatest common factor 520,903 is 1.
Lets's calculate LCM of 315,668
Given numbers has no common factors except 1. So, there LCM is their product i.e 210420
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/210420
Therefore, the GCF of Fractions 520/315,903/668 is 1/210420
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 315,668 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(315,668) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(315,668) x common factors =1 x 1 = 1
LCM(315,668) = ( 315 × 668 ) / 1
LCM(315,668) = 210420 / 1
LCM(315,668) = 210420
Here are some samples of GCF of Fractions calculations.
