Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 681/13,217/353
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 681,217
Greatest Common Factor of Numerators i.e. GCF of 681,217 is 1 .
LCM of Denominators means LCM of 13,353 as per the given fractions.
LCM of 13,353 is 4589 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 681,217
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 681
List of positive integer factors of 681 that divides 681 without a remainder.
1,3,227,681
Factors of 217
List of positive integer factors of 217 that divides 217 without a remainder.
1,7,31,217
Greatest Common Factor
We found the factors 681,217 . The biggest common factor number is the GCF number.
So the greatest common factor 681,217 is 1.
Lets's calculate LCM of 13,353
Given numbers has no common factors except 1. So, there LCM is their product i.e 4589
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4589
Therefore, the GCF of Fractions 681/13,217/353 is 1/4589
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 13,353 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(13,353) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(13,353) x common factors =1 x 1 = 1
LCM(13,353) = ( 13 × 353 ) / 1
LCM(13,353) = 4589 / 1
LCM(13,353) = 4589
