Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 1391/19,3210/393
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 1391,3210
Greatest Common Factor of Numerators i.e. GCF of 1391,3210 is 107 .
LCM of Denominators means LCM of 19,393 as per the given fractions.
LCM of 19,393 is 7467 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 1391,3210
107 | 1391, 3210 |
13, 30 |
∴ So the GCF of the given numbers is 107 = 107

1,13,107,1391
Factors of 3210
List of positive integer factors of 3210 that divides 3210 without a remainder.
1,2,3,5,6,10,15,30,107,214,321,535,642,1070,1605,3210
Greatest Common Factor
We found the factors 1391,3210 . The biggest common factor number is the GCF number.
So the greatest common factor 1391,3210 is 107.
Lets's calculate LCM of 19,393
Given numbers has no common factors except 1. So, there LCM is their product i.e 7467
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 107/7467
Therefore, the GCF of Fractions 1391/19,3210/393 is 107/7467
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 19,393 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,393) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(19,393) x common factors =1 x 1 = 1
LCM(19,393) = ( 19 × 393 ) / 1
LCM(19,393) = 7467 / 1
LCM(19,393) = 7467
Here are some samples of GCF of Fractions calculations.
