Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 23/16,91/35,17/20,29/260
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 23,91,17,29
Greatest Common Factor of Numerators i.e. GCF of 23,91,17,29 is 1 .
LCM of Denominators means LCM of 16,35,20,260 as per the given fractions.
LCM of 16,35,20,260 is 7280 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 23,91,17,29
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 29 that divides 29 without a remainder.
1,29
Greatest Common Factor
We found the factors 23,91,17,29 . The biggest common factor number is the GCF number.
So the greatest common factor 23,91,17,29 is 1.
Lets's calculate LCM of 16,35,20,260
2 | 16, 35, 20, 260 |
2 | 8, 35, 10, 130 |
5 | 4, 35, 5, 65 |
4, 7, 1, 13 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 4 x 7 x 1 x 13 = 7280
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7280
Therefore, the GCF of Fractions 23/16,91/35,17/20,29/260 is 1/7280
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 16,35,20,260 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(16,35,20,260) = 1
common factors(in case of two or more numbers have common factors) = 400
GCF(16,35,20,260) x common factors =1 x 400 = 400
LCM(16,35,20,260) = ( 16 × 35 × 20 × 260 ) / 400
LCM(16,35,20,260) = 2912000 / 400
LCM(16,35,20,260) = 7280
