Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 19/684,70/1855
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 19,70
Greatest Common Factor of Numerators i.e. GCF of 19,70 is 1 .
LCM of Denominators means LCM of 684,1855 as per the given fractions.
LCM of 684,1855 is 1268820 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 19,70
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 19
List of positive integer factors of 19 that divides 19 without a remainder.
1,19
Factors of 70
List of positive integer factors of 70 that divides 70 without a remainder.
1,2,5,7,10,14,35,70
Greatest Common Factor
We found the factors 19,70 . The biggest common factor number is the GCF number.
So the greatest common factor 19,70 is 1.
Lets's calculate LCM of 684,1855
Given numbers has no common factors except 1. So, there LCM is their product i.e 1268820
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1268820
Therefore, the GCF of Fractions 19/684,70/1855 is 1/1268820
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 684,1855 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(684,1855) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(684,1855) x common factors =1 x 1 = 1
LCM(684,1855) = ( 684 × 1855 ) / 1
LCM(684,1855) = 1268820 / 1
LCM(684,1855) = 1268820
Here are some samples of GCF of Fractions calculations.
