Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 35/49,125/80,338/81
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 35,125,338
Greatest Common Factor of Numerators i.e. GCF of 35,125,338 is 1 .
LCM of Denominators means LCM of 49,80,81 as per the given fractions.
LCM of 49,80,81 is 317520 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 35,125,338
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 35
List of positive integer factors of 35 that divides 35 without a remainder.
1,5,7,35
Factors of 125
List of positive integer factors of 125 that divides 125 without a remainder.
1,5,25,125
Factors of 338
List of positive integer factors of 338 that divides 338 without a remainder.
1,2,13,26,169,338
Greatest Common Factor
We found the factors 35,125,338 . The biggest common factor number is the GCF number.
So the greatest common factor 35,125,338 is 1.
Lets's calculate LCM of 49,80,81
Given numbers has no common factors except 1. So, there LCM is their product i.e 317520
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/317520
Therefore, the GCF of Fractions 35/49,125/80,338/81 is 1/317520
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 49,80,81 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(49,80,81) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(49,80,81) x common factors =1 x 1 = 1
LCM(49,80,81) = ( 49 × 80 × 81 ) / 1
LCM(49,80,81) = 317520 / 1
LCM(49,80,81) = 317520
Here are some samples of GCF of Fractions calculations.
